74LVC1G3157
SINGLE-POLE DOUBLE-THROW ANALOG SWITCH
Description
Pin Assignments
The 74LVC1G3157 is a single-pole, double-throw analog switch. The
device is designed for operation with a power supply range of 1.65V to
5.5V. The bidirectional switch can handle signal amplitudes between
Vcc and Ground. The OFF state impedance of the switch is typically
50MΩ while the ON state is typically 6Ω.
