The SN74LVC1G3157-Q1 device is a single-pole double-throw (SPDT) analog switch designed for 1.65V to 5.5V VCC operation. The SN74LVC1G3157 device can handle analog and digital signals. The 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.
