Description
The FSA3157B 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 5.5V VCC operating
range. The control input tolerates voltages up to 5.5V,
independent of the VCC operating range.
