Low-Voltage SPDT Analog Switch or 2:1 Multiplexer/ De-multiplexer Bus Switch
NC7SBU3157, FSAU3157
General Description The NC7SBU3157 / FSAU3157 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−beforemake 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 5.5V, independent of the VCC operating range.
