SINGLE-POLE,DOUBLE-THROW
ANALOG SWITCH
DESCRIPTION
The UTC U74LVC3157 is
a
low voltage single-pole,
double-throw (SPDT) analog switch intending for use in chopping,
modem, signal gating, and signal multiplexing for analog-to-digital
and digital-to-analog conversion systems.
FEATURES
* Useful in Both Analog and Digital Applications
* Rail-to-Rail Signal Handing
* Low ON Resistance:<10Ω on Typical @ 3.3V VCC
* Broad VCC Operating Range:1.65V to 5.5V
* Over-Voltage Tolerance of Control Input to 7.0V
