ProductDescription

Pericom Semiconductor’s PI3C series of Bus Switch circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading speed.

ThePI3C16210isconfiguredasa20-bit,2-portbusswitchdesigned

with a low ON resistance (5 Ohm) allowing inputs to be connected

directly to outputs. The bus switch creates no additional

propagational delay or additional ground bounce noise. The switch

is turned ON by the Bus Enable (xOE) input signal.
