Product Description
Pericom Semiconductors PI3C series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry performance.
The PI3C32X384, and PI3C32X2384 are 2.5V or 3.3Volt, high-
bandwidth 20-bit, 2-port bus switches designed with a low ON
resistance 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. Four bus enable signals are provided,
one for each of the upper and lower five bits of the two 10-bit buses.
The PI3C32X2384 is designed with an internal 25ohm resistor
reducing noise reflection in high-speed applications.
