Low-Voltage SPDT Analog Switch or 2:1 Multiplexer / De-multiplexer Bus Switch
NC7SB3157, FSA3157
Description The NC7SB3157 / FSA3157 is a high−performance,
single−pole / double−throw (SPDT) analog switch or 2:1 multiplexer / de−multiplexer bus switch.
The device is fabricated with advanced sub−micron CMOS technology to achieve high−speed enable and disable times and low on resistance. The break−before−make select circuitry prevents disruption of signals on the B Port due to both switches temporarily being enabled during select pin switching. The device is specified to operate over the 1.65 to 5.5 V VCC operating range. The control input tolerates voltages up to 5.5 V, independent of the VCC operating range.
