DESCRIPTION/ORDERING INFORMATION
This single-pole double-throw (SPDT) analog switch is designed for 1.65-V to 5.5-V V
CC
operation.
The SN74LVC1G3157 can handle both analog and digital signals. The device permits signals with amplitudes of
up to V
CC
(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.
