Package Description
General Description
The NC7SB3157 / FSA3157 is a high-performance, sin-
gle-pole / double-throw (SPDT) analog switch or 2:1 mul-
tiplexer / 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 speci-
fied to operate over the 1.65 to 5.5V V
range. The control input tolerates voltages up to 5.5V,
independent of the V
CC
operating range.
