3 Description

This single channel single-pole double-throw (SPDT)

analog switch is designed for 1.65V to 5.5V VCC

operation.

The SN74LVC1G3157 device handles both analog

and digital signals. The SN74LVC1G3157 device

allows signals with amplitudes of up to VCC (peak) to

be transmitted in either direction.

Applications include signal gating, chopping,

modulation or demodulation (modem), and signal

multiplexing for analog-to-digital and digital-to-analog

conversion systems.
