Description

Pericom Semiconductor's PI3C series of logic circuits are produce using the Company's advanced submicron CMOS technology achieving industry leading performance.

In the  PI3C series ,the PI3C3244 features a set of 2.5V or 3.3V 8-bit bus switches, hich is a pinout and function compatible with the P74FCT244T, 4F244, and 74ALS/AS/LS2448-bit drivers. Two enable signals BEn) turn the switches on similar to the enable signals of the 244.

The  PI3C series  bus switch create no additional propagation delay or ground ounce noise. It is very useful in switching signals that have high andwidth (>400 MHz).
