Product Description
Pericom Semiconductor聮s PI5C series of Bus Switch circuits are
produced using the Company聮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 (5ohm) 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 聳1V.
