DG4157E Analog Switches

Vishay’s high-performance single-pole, double-throw (SPDT) analog switches designed for 1.65 V to 5.5 V operation with a single power rail

Image of Vishay Siliconix's DG4157E Analog SwitchesVishay’s DG4157E analog switches were designed with high-density CMOS technology. These devices achieve low on-resistance of 0.86 Ω at a 4.5 V power supply, low power consumption, and fast switching speeds. The DG4157E can handle both analog and digital signals and permits signals with amplitudes of up to V+ to be transmitted in either direction. Its control logic inputs can go over V+ up to 5.5 V. The control logic input high threshold is guaranteed as low as 1.8 V over the power supply range up to 5.5 V. It features break before make switching performance. Its -3 dB bandwidth is typically 152 MHz. A powered-off protection circuit is built into the switch to prevent an abnormal current flow from COM pin to V+ during the power-down condition. Each output pin can withstand greater than 7 kV (human body model).

Operation temperature is specified from -40°C to +85°C. The DG4157E is available in the ultra-compact µDFN-6L and SC-70-6 packages.
