Product Description

PericomSemiconductor’sPI5Cseriesoflogiccircuitsareproduced

using the Company’s advanced 0.8 micron CMOS technology,

achieving industry leading performance.

The PI5C32861 is a 10-bit, 2-port bus switch designed with a low

ON resistance that permits inputs to be connected directly to

outputs. The bus switch creates no additional propagational delay

or additional ground bounce noise. The switches are turned ON

by the Bus Enable (BE) input signal. The PI5C32861 is designed

with an internal 25Ω resistor that reduces noise reflection in high-

speed applications

Product Features

• Near zero propagation delay

•5

Ω switches with 25Ω series resistor connect inputs

to outputs

•

Direct bus connection when switches are ON

•

Ultra Low Quiescent Power (0.2µA Typical)

– Ideally suited for notebook applications

• Packages available:

– 24-pin 150 mil wide plastic QSOP (Q)

– 24-pin 300 mil wide plastic SOIC (S)
