Product Description
Pericom Semiconductor聮s PI3B series of logic circuits are produced
using the Company聮s advanced submicron CMOS technology,
achieving industry leading performance.
The PI3B33X257 is a 3.3V, 24:12 multiplexer/demultiplexer with
three-state outputs. Inputs can be connected to outputs with low
on resistance (5 ohm) with no additional ground bounce noise or
propagation delay.
