Block Diagram
Description
Pericom Semiconductor’s PI3B16234 is a 16-bit to 32-bit mux/
demux switch. Industry leading advantages include almost zero
propagation delay of 500ps because of 8-ohm channel resistance
and low I/O capacitance. A1 port demultiplexes to either port B1 or
B2. The switch is bidirectional.
