DESCRIPTION/ORDERING INFORMATION
This single-pole, double-throw (SPDT) analog switch is designed for 1.65-V to 5.5-V VCC operation.
The SN74LVC1G3157 can handle both 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.
