US5C3257

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
