Product Description
Pericom Semiconductor’s PI3B series of BusSwitch circuits are produced in the Company’s advanced 0.35 micron CMOS technology, achieving industry leading speed. The PI3B16210 is configured as 3.3 volt 20-bit, 2-port bus switches 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 (xOE) input signal. The PI3B162210 device has a built-in 25-ohm series resistor to reduce noise resulting from reflections, thus eliminating the need for an external terminating resistor.
