Description
This device consists of a low-power voltage comparator designed specifically to
operate from a single supply over a wide range of voltages. Operation from split
power supplies is also possible.
This comparator also has a unique characteristic in that the input common-mode
voltage range includes ground, even though operated from a single power supply
voltage.

1. Output voltage can be set up to 36 V even if the VCC is lower.
2. Short-circuits from the output to VCC + can cause excessive heating and potential destruction. The maximum output current
is approximately 20 mA independent of the magnitude of VCC +.
3. Short-circuits can cause excessive heating. These values are typical.
4. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a 1.5 kΩ resistor
between two pins of the device. This is done for all couples of connected pin combinations while the other pins are floating.
5. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between two pins of the
device with no external series resistor (internal resistor < 5 Ω). This is done for all couples of connected pin combinations
while the other pins are floating.
6. Charged device model: all pins and package are charged together to the specified voltage and then discharged directly to
ground through only one pin. This is done for all pins.

1. The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3 V. The
upper end of the common-mode voltage range is (VCC +) – 1.5 V, but either or both inputs can go to 30 V without damage.

1. At the output switch point, Vo ≈ 1.4 V, RS = 0 Ω with (VCC +) from 5 V to 30 V, and over the full input
common-mode range (0 V to (VCC +) – 1.5 V).
2. The direction of the input current is out of the IC due to the PNP input stage. This current is essentially
constant, independent of the state of the output, so there is no load charge on the reference of input lines.
3. Positive excursions of the input voltage may exceed the power supply level. As long as the other voltage
remains within the common-mode range, the comparator will provide a proper output state. The low input
voltage state must not be less than –0.3 V (or 0.3 V below the negative power supply, if used)
4. The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals,
300 ns can be obtained.
