Product Description
Pericom Semiconductors PI3C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry leading performance.
The PI3C34X245 is a 2.5V or 3.3V, 32-bit, 2-port bus switch designed
with a low ON resistance (5Ω) 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. It is very useful in switching
signals that have high bandwidth (>400 MHz).
