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