Product Description
Pericom Semiconductors PI3B series of logic circuits are produced
using the Companys advanced submicron CMOS technology.
The PI3B16212 and PI3B162212 are 3.3 volt, 24-bit bus exchange
switches designed with low ON resistance allowing inputs to be
connected directly to outputs. The devices operate as a 24-bit bus
switch or as a 12-bit exchanger, providing data exchange between
the four signal ports via the data select pins (S0-S2).
The PI3B162212 device has a built-in 25-ohm series resistor to
reduce reflection noise, thus eliminating the need for an external
terminating resistor.
