Product Description
Pericom Semiconductors PI3B series of logic circuits are produced
using the Companys advanced submicron CMOS technology,
achieving industry leading performance.
The PI3B3257 is a 3.3 Volt, Quad 2:1 multiplexer/demultiplexer with
three-state outputs that is pinout and function compatible with the
PI74FCT257T, 74F257, and 74ALS/AS/LS257. Inputs can be
connected to outputs with low ON resistance (5 ohms) with no
additional ground bounce noise or propagation delay.
