Logic Block Diagram
Product Description
Pericom Semiconductors PI5C series of logic circuits are produced
using the Companys advanced 0.8 micron CMOS technology.
The PI5C16209 and PI5C162209 are 18-bit bus exchange switches
designed with a low ON resistance (5Ω) allowing inputs to be
connected directly to outputs. This device operates as a 18-bit bus
switch or a 9-bit exchanger, which provides data exchanging
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 because of reflections, thus eliminating the need for
an external terminating resistor.
