MM54HC253/MM74HC253  
Dual 4-Channel TRI-STATE Multiplexer  
É
General Description  
The MM54HC253/MM74HC253 utilizes advanced silicon-  
gate CMOS technology to achieve the low power consump-  
tion and high noise immunity of standard CMOS integrated  
circuits, along with the capability to drive 10 LS-TTL loads.  
The large output drive and TRI-STATE features of this de-  
vice make it ideally suited for interfacing with bus lines in  
bus organized systems. When the output control input is  
taken high, the multiplexer outputs are sent into a high im-  
pedance state.  
The 54HC/74HC logic family is functionally and pinout com-  
patible with the standard 54LS/74LS logic family. All inputs  
are protected from damage due to static discharge by inter-  
nal diode clamps to V  
and ground.

Wide power supply range: 2V6V  
Low quiescent current: 80 mA maximum (74HC Series)  
Low input current: 1 mA maximum  
Fanout of 10 LS-TTL loads  
When the output control is held low, the associated multi-  
plexer chooses the correct output channel for the given in-  
put signals determined by the select A and B inputs.
