Product Description
Pericom Semiconductor聮s PI3B series of logic circuits are produced
in the company聮s advanced submicron CMOS technology.
The PI3B34X245 is a 3.3V, 32-bit, 2-port bus switch. Four enable
signals (BEn) turn the switches on. The bus switch creates no
additional propagational delay or additional ground bounce noise.
