DESCRIPTION

The UTC US5C3257 is a QUAD 2:1 multiplexer/demultiplexer

with low on-resistance and is pinout and function compatible with

the TTL device. Inputs can be connected to outputs with low on

resistance (5Ω) with no additional ground bounce noise or

propagation delay.

FEATURES

* 5Ω switches connect inputs to outputs

* ESD protection on pin

* Near zero propagation delay

* Ultra Low Quiescent Power (0.2µA Typical)

–Ideally suited for notebook applications

* Direct bus connection when switches are ON

* Pin compatible with U74 series logic devices
