Pericom Semiconductors PI3B series of logic circuits are produced
using the Companys advanced submicron CMOS technology.
The PI3B32X245 is a 3.3V,16-bit, 2-port bus switch. Two enable
signals (BEn) turn the switches on. The bus switch creates no
additional propagational delay or additional ground bounce noise.
