Product Description
Pericom Semiconductor鈥檚 PI3B series of logic circuits are produced
in the Company鈥檚 advanced 0.35 micron CMOS technology.
The PI3B16209 and PI3B162209 are 3.3 volt, 18-bit bus exchange
switches designed with a low ON resistance (5鈩? allowing inputs
to be connected directly to outputs. The devices operate as an 18-bit
bus switch or as a 9-bit exchanger, providing data exchange between
the four signal ports via the data select pins (S0-S2).
The PI5C162209 device has a built-in 25-ohm series resistor to
reduce noise resulting from reflections, thus eliminating the need
for an external terminating resistor.
