ProductDescription

PericomSemiconductor’s PI3Cseriesof logiccircuitsareproduced

using the Company’s advanced submicron CMOS technology.

The PI3C16234 is a 16-bit to 32-bit mux/demux switch. Industry

leading advantages include almost zero propagation delay of 500ps

because of the 9ohm channel resistance and low I/O

capacitance. A1 port demultiplexes to either port B1 or B2 and the

switch is bidirectional.
