General 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-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 5.5V VCC operating range. The
control input tolerates voltages up to 5.5V, independent of the VCC
operating range.
