Product Description
Pericom Semiconductor聮s PI5C series of BusSwitch circuits
are produced in the Company聮s advanced submicron CMOS
technology, achieving industry leading speed.
The PI5C16214 and PI5C162214 are 3-to-1 bus-select switches
designed with a low ON resistance (5ohm) allowing inputs to be
connected directly to outputs. These devices operate as 12-bit bus
switches via the data select pins (S0-S2).
The PI5C162214 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
