MM54HCT253/MM74HCT253  
Dual 4-Channel TRI-STATE Multiplexer  
É
General Description  
The MM54HCT253/MM74HCT253 utilizes advanced sili-  
con-gate CMOS technology to achieve the low power con-  
sumption 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 device make it ideally  
suited for interfacing with bus lines in bus organized sys-  
tems. When the output control input is taken high, the multi-  
plexer outputs are sent into a high impedance 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.

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.
