Product Description
Pericom Semiconductors PI5C series of Bus Switch circuits are produced using the Companys advanced submicron CMOS technology, achieving industry leading speed.
The PI5C16861C is configured as a 20-bit, 2-port bus switch designed with a low ON resistance (5 ohms) 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 PI5C162861C device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor.
