Pericom SemiconductorÂs PI5C series of logic circuits are produced
using the CompanyÂs advanced 0.8 micron CMOS technology,
3 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
4 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
