Product Description:
Pericom Semiconductor聮s PI5C series of BusSwitch circuits are
produced in the Company聮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 (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 (xOE) input signal.
The PI5C162210 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
