Product Description:
Pericom Semiconductor’s PI5C series of BusSwitch circuits are
produced in the Company’s advanced sub-micron CMOS
technology, achieving industry leading speed.
The PI5C16210 is configured as 20-bit, 2-port bus switches
designed 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
switches are turned ON by the Bus Enable (xOE) input signal.
