Product Description
Pericom Semiconductor聮s PI5C series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology.
The PI5C16212 and PI5C162212 are 24-bit bus exchange switches
designed with a low ON resistance allowing inputs to be connected
directly to outputs. This device operates as a 24-bit bus switch
or a 12-bit exchanger that provides data exchanging between
the four signal ports via the data select pins (S0-S2).
To reduce noise resulting from reflections, the PI5C162212 has a
built-in 25-ohm series resistor that eliminates the need for an
external terminating resistor.
