Product Description
Pericom Semiconductor聮s PI3B series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology.
The PI3B16213 is a 3.3 volt, 24-bit bus-exchange switch designed
with a low ON resistance allowing connections to be made with
minimal propagation delay. This device operates either as a 24-bit
or as a 12-bit bus switch, providing data exchange between the four
signal ports via the data-select (S0-S2) terminals.
