Product Description
Pericom Semiconductor聮s PI3C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3C34X461 is a 40-bit, 2-port bus switch designed with a low
ON resistance (5鈩? allowing 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.
