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.
