Product Description

Pericom Semiconductor’s PI3B series of logic circuits are produced in the Company’s advanced 0.35 micron 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 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.
