10-Bit, 2-Port Bus Switch
with 25
Series Resistor
Product Description
Pericom Semiconductors PI5C series of logic circuits are produced
using the Companys 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 25
resistor that reduces noise reflection in high-
speed applications
Product Features
Near zero propagation delay
5
switches with 25
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)
