ProductDescription

PericomSemiconductor’sPI3Cseriesoflogiccircuitsareproduced

using the Company’s advanced submicron CMOS technology,

achieving industry leading performance.

ThePI3C32160isa16-to32-bitdemultiplexerbusswitch.Industry

leading advantages include a propagation delay of 500ps, resulting

from 9 ohms channel resistance and low I/O capacitance. A port

demultiplexes to either 1B or 2B and the switch is bidirectional.

Application

PCI Hot Plugging.
