3 Description
The SN74LVC1G3157-Q1 device is a single-pole
double-throw (SPDT) analog switch designed for
1.65-V to 5.5-V 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.
