Description

This single channel single-pole double-throw (SPDT) analog switch is designed for 1.65-V to 5.5-V VCC operation.

The SN74LVC1G3157 device can handle both analog and digital signals. The SN74LVC1G3157 device permits 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.
