ft3157 Overview
The ft3157 is a low on-resistance high speed single-pole dual-throw (SPDT) analog switch suitable for use as an analog or digital 2:1 multiplexer/demultiplexer. It has a digital select input (IN), two independent inputs or outputs (NO and NC) and a mon input or output (). Schmitt-trigger action at the digital input makes the circuit tolerant to slower input rise and fall times.
