Product Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced submicron 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 25ohm resistor that reduces noise reflection in high-
speed applications
