Description
Pericom Semiconductor’s PI5C series of logic circuits are produced
in the Company’s advanced submicron CMOS technology.
The PI5C34X245 is a 32-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.
