Product Description

Pericom Semiconductor’s PI5C series of Bus Switch circuits are

produced using the Company’s advanced submicron CMOS

technology, achieving industry leading speed.

The PI5C16862C is configured as a 20-bit, 2-port bus switch

designed with a low ON resistance (5Ω) allowing inputs to be

connected directly to outputs. The bus switch creates no additional

propagational delay or additional ground bounce noise. The

switches are turned ON by the Bus Enable (BEx) input signal.

The PI5C16862C can withstand undershoot of up to –1V.
