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.
