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.
