Clock/Timing - Clock Buffers, Drivers
Products in the clock buffer & driver integrated circuit family are used to aid the dissemination of signals throughout a system, most commonly the frequency/time reference signals used to synchronize activity within the system. While the function most commonly performed is that of buffering, the replication of a signal from some source to isolate it from the influence of a driven load, some devices in the family perform additional functions such as selective rerouting of the buffered signals, division of signal frequency by some integer value, or translation of electrical signaling format used.

Embedded - Microcontrollers
Microcontroller products are relatively complex, user-programmable digital logic devices. Closely related to devices considered microprocessors, the distinction between the two reduces largely to the manufacturer's choice of noun, though by tradition microcontrollers integrate working memory, are more likely to incorporate mixed-signal peripherals and tend to be used with simpler software paradigms oriented toward repetitive execution of a predefined series of tasks.
Embedded - Microprocessors
Microprocessor products are integrated circuits used for information and data processing. They are differentiated from similar products that are considered microcontrollers primarily by the manufacturer's choice of term, though by tradition microprocessors do not integrate working memory within the device, are less likely to integrate mixed-signal peripherals, and likely to be used under more complex software paradigms involving the use of an operating system to manage the concomitant execution of multiple tasks.
Interface - Analog Switches - Special Purpose
Special Purpose Analog Switches route analog signals via a solid state device. The differentiator in this family is that these Analog switches target a specific application, and as such have distinguishing features not typically found in general purpose Analog switches.

Interface - I/O Expanders
Devices in this family are used in conjunction with microcontrollers, microprocessors, or similar devices for the purpose of increasing the number of signal connections available for connecting peripheral devices. The typical concept of operation involves the use of serial communications requiring only a few I/O lines on the host device to read/write the status of many input/output pins on the expander device. The technique exchanges speed of communication for increased connectivity, and is best suited for applications where fast response is not critical, such as in many human interface applications.

They are commonly used for human interface applications.
Interface - Signal Buffers, Repeaters, Splitters
Products within the signal buffer, repeater, and splitter family are used in context of transmitting digital information over electrically long interconnects or cable systems.

Logic - Buffers, Drivers, Receivers, Transceivers
Logic buffers, drivers, receivers and transceivers allow isolated access to logic signals from one circuit for use in another circuit. Buffers pass their input signal, either unchanged or inverted, to their output and may be used to clean up a weak signal or drive a load. In a boolean logic simulator, a buffer is mainly used to increase propagation delay. Logic receivers and transceivers allow isolated communication between data buses.
Logic - Comparators
Products in the logic comparator family are used to generate an output based on comparison of information represented in a digital format; identity types indicate whether or not two inputs are identical, magnitude types also indicate which of the two inputs is greater when they are not identical. They are distinct from devices that compare the magnitude of two analog inputs, which are known as linear comparators and are catalogued separately.
Logic - Counters, Dividers
Counter and divider ICs are digital logic devices which tally the number of logic transitions that occur at their inputs, and resent the accumulated count using multiple parallel outputs and/or generate a single output signal transition in response to the application of some integer number of input signal transitions. In addition to simple event counting, they find use in a variety of frequency synthesis applications.
Logic - Flip Flops
Flip-flops are elementary digital memory devices capable of storing a single logic state or "bit" of information. They have at least two inputs; one or more to communicate the data to be stored and another to indicate the point in time to store it. Different flip-flop types such as D (delay), SR (Set-Reset), and JK respond differently to the signals presented to their inputs and can be used to implement different logical functions. They differ from latches in that they are edge sensitive devices, whose retained logic state changes only at the moment a valid clock signal is received.
Logic - Gates and Inverters - Multi-Function, Configurable
Products in the configurable logic gate family perform elementary logic operations on individual logic signals in a fashion similar to standard logic gates, but without the limitation of being constrained to one specific function such as AND, NAND, etc. They are commonly implemented using a small number of logic gates internally, selected and interconnected to allow the overall logic function that is realized to be configured by the choice of which among several inputs the operating data is applied to, and the logic state to which any unused inputs are driven.
Logic - Gates and Inverters
Products in the logic gate and inverter family perform elementary logical operations on individual logic signals such as AND, NOT, OR, etc. Unlike flip-flops they do not have a capacity to store information and respond immediately to the signals presented to their inputs. Though long supplanted by implementations in integrated circuit form for realizing complex functions, discrete gates remain available for use in circumstances where only very simple logical functions are needed.
Logic - Latches
Latches are elementary digital memory devices similar to flip-flops, but different in that the retained logic state can change at any time a latch enable (or similarly named) signal is in a valid logic state. Latches described as "transparent" further allow the device outputs to reflect the current state of the inputs while the latch enable signal is valid, as opposed to changing state only when the retained state has been fixed.
Logic - Multivibrators
Multivibrators are simple two-state devices commonly considered digital logic components, though their typical manners of use are largely analog in character. Monostable types, also called "one-shots", have one stable state; though application of a trigger signal can cause them to leave this state for a period of time usually determined by the value of a connected capacitor. These are useful for applications such as de-bouncing switch contacts. Astable types have no stable state, and transition between two states continuously at a frequency which again is usually determined by the value of a connected capacitor.
Logic - Parity Generators and Checkers
Devices in the parity generator and checker logic family are component-level devices used to evaluate the number of bits in a digital word that are set to 1, and generate (or evaluate) an additional parity bit which indicates whether the number of bits in the word set to 1 is even or odd. This function is commonly used as a simple means of detecting data errors that may have been introduced during transmission.
Logic - Shift Registers
Shift registers are low-level logic devices commonly used to convert data in the form of digital logic signals between serial and parallel formats, or to move the position of the data bits within a digital word. Typically implemented using an array of flip-flops integrated into one device, shift registers are a common component of more highly integrated logic devices, though they remain available for applications such as I/O expansion where the function in a discrete form may prove useful.
Logic - Signal Switches, Multiplexers, Decoders
Logic type signal switch, multiplexer, and encoder ICs are used for routing and selection of electrical signals used to represent data in digital format. They differ from similar products designed for use with analog signals in that they are designed to preserve information represented as one of two electrical states, rather than as an infinitely variable quantity within two outer limits.
Logic - Specialty Logic
Specialty Logic ICs are designed to provide an application specific logic output type such as BCD rate multiplication, addressable scan port, bus termination array, CML driver, comparator, ABT scan test, binary full adder, complimentary pair plus inverter, configurable buffer, contact bounce eliminator, crystal oscillator, delay element, differential receiver, LVTTL-to-GTLP transceiver, memory decoder, power good detector, and frequency divider.
Logic - Translators, Level Shifters
Logic translator or level shifter ICs are devices used to pass information between digital logic devices that are operating from different/incompatible supply voltages, or which implement different signaling methods. Examples might include the connection of a digital-output sensor requiring a 5 V supply to an FPGA with a 3.3 V I/O supply, or converting between single-ended signaling methods like CMOS or TTL and differential techniques, such as PECL or LVDS.
Logic - Universal Bus Functions
Products in the universal bus function family are component-level products used for handling or operating on a series of (usually 8 or more) parallel logic signals known as a bus. Functions performed include temporary storage of data to be transmitted or received, buffering to allow a device such as a microprocessor having a limited output current capacity to transmit data over long interconnects at high speed, rotation or shifting of bit order within the bus, and others.
Memory is a semiconductor device that is used as data storage device on an integrated circuit. These devices are available in several formats CBRAM, DRAM, EEPROM, EERAM, EPROM, Flash, FRAM, NVSRAM, PCM (PRAM), PSRAM, RAM, and SRAM in either Non-Volatile or Volatile.

PMIC - AC DC Converters, Offline Switchers
Products in this family are component-level control devices used to construct equipment that converts AC utility power to a DC form, typically at a much reduced voltage. Devices which incorporate the primary switching element for the system and those which do not are both included. Due to the high ratio of input to output voltages and need for isolation commonly encountered in such systems, they are often used in conjunction with an external transformer.

PMIC - Full, Half-Bridge Drivers
Devices in the bridge driver PMIC (Power Management Integrated Circuit) family incorporate two or more power transistors along with circuitry required to operate them as switches under the control of an external device. The transistors are typically configured internally in series-connected pairs known as half-bridges, such that the junction between any given pair can be connected to either of two power supply rails. They are commonly used to translate low-level signals provided by a control device such as a microcontroller into the higher power signals required to operate an actuator such as a stepper or brushless motor.
PMIC - Gate Drivers
Gate driver Power Management Integrated Circuits (PMICs) are devices that provide isolation, amplification, reference shifting, bootstrapping, or other functions necessary to interface signals from a control device in a power conversion application to the semiconductor devices (usually FETs or IGBTs) through which the power being controlled passes. The exact functions offered by any particular device vary, but correlate with the semiconductor configuration it is adapted to drive.
PMIC - LED Drivers
Devices in the LED driver PMIC (Power Management Integrated Circuit) family are used to supply a current flow of controlled value to a load, typically a Light Emitting Diode, from a power source having a nominally fixed voltage. Key differentiators from the very similar products designed for voltage regulation include a characteristically lower feedback voltage (to improve system efficiency) and high prevalence of provisions for external control of the device's operating point, used to implement dimming functions in lighting applications.
PMIC - Lighting, Ballast Controllers
Products in this family are used to implement control and regulation functions necessary or useful for the operation of non-LED lighting agents such as fluorescent, electroluminescent, and HID lamps. The specific function set incorporated into a given device varies with the intended use, and available products may or may not incorporate resources for direct manipulation of the power supplied to the driven load.
PMIC - Motor Drivers, Controllers
Products in the motor driver and controller PMIC (Power Management Integrated Circuit) family are used to control or manipulate the application of power from some source to electric motors or related electromechanical actuators. The precise functionality and feature sets implemented vary widely depending on the characteristics of the intended load and expected application, ranging from simple open-loop speed control for brushed motors to advanced, closed-loop, stepper-based motion control.
PMIC - PFC (Power Factor Correction)

The different modes are average current, boundary conduction, continuous conduction, critical conduction, current controlled frequency foldback, discontinuous, and discontinuous conduction with a frequency switching of adjustable and 6kHz to 1.7MHz.
PMIC - Power Distribution Switches, Load Drivers
Products in this family are solid-state devices used to connect or interrupt the flow of current to a supported load, under the direction of a logic-level control signal that is of itself incapable or unsuitable for supplying the load. They integrate the semiconductor switching device used to interrupt current flow and incorporate additional supporting components/functions such as over-voltage clamping, current limiting, and under-voltage lockouts, which differentiate them from similar IC and discrete components.
PMIC - Power Management - Specialized

PMIC - Voltage Reference
Products in the voltage reference family are used to derive an electrical potential having a stable, well-established value from a source of more uncertain character, for use as a standard of comparison in measurement, control, and similar applications. While their functional behavior may be similar to that of linear voltage regulators used for purposes of bulk power regulation, voltage reference devices are not adapted for use as such; their performance as standards of comparison has a generally inverse relationship with increasing output current capacity or actual current drawn by a load.
PMIC - Voltage Regulators - DC DC Switching Controllers
PMIC (Power Management Integrated Circuit) DC to DC switching controllers are voltage regulation ICs used in high efficiency circuits configured to generate output supply voltages above (boost or step-up) or below (buck or step-down) the input supply. Other topologies may include; buck-boost, flyback, forward, cuk, SEPIC, full bridge, half bridge, and push-pull. They differ from linear regulators that require minimum voltages and "burn off" excess voltage.
PMIC - Voltage Regulators - DC DC Switching Regulators
Products in the DC-DC switching regulator PMIC (Power Management Integrated Circuit) family are component-level devices used in applications requiring stabilization of a DC input voltage and/or transformation thereof to an output voltage of different magnitude. They are distinguished from similar products called "controller" PMICs by virtue of integrating the main switching element through which the power delivered by the device passes.
PMIC - Voltage Regulators - Linear + Switching
Products in this family are used for constructing circuits that perform a DC-DC conversion or voltage regulation function, using a combination of switch-mode and linear regulator functions. While exact topologies vary, the underlying goal of such products is to obtain a combination of the efficiency advantages of switch-mode techniques with the low-noise qualities of linear regulation.
PMIC - Voltage Regulators - Linear
Linear voltage regulators are used to provide a stable output voltage that is nominally invariant with respect to changes in load current, input voltage, or environmental factors. Their operating principle requires that the input voltage be maintained above the desired output voltage by some minimum amount, and function on the basis of converting whatever excess voltage is present at the input to heat. While this renders them less efficient than switch-mode voltage regulators for most applications, they are often better suited for applications with high sensitivity to noise.
PMIC - Voltage Regulators - Special Purpose
Products in this family are used for power manipulation, transformation, or conversion of some form, and are adapted for specific applications of an esoteric nature.
