MM54HCT157/MM74HCT157 Quad  
2-Input Multiplexer  
MM54HCT158/MM74HCT158  
Quad 2-Input Multiplexer (Inverted Output)  
General Description  
These high speed QUAD 2-to-1 line data selector/multiplex-  
ers utilize advanced silicon-gate CMOS technology. They  
possess the high noise immunity and low power consump-  
tion of standard CMOS integrated circuits, as well as the  
ability to drive 10 LS-TTL loads.  
The 54HCT/74HCT logic family is functionally as well as  
pin-out compatible with the standard 54LS/74LS logic fami-  
ly. All inputs are protected from damage due to static dis-  
charge by internal diode clamps to V  
and ground.

Features

These devices each consist of four 2-input digital multiplex-  
ers with common select and OUTPUT ENABLE inputs. On  
the MM54HCT157/MM74HCT157, when the OUTPUT EN-  
ABLE input is at logical ‘‘0’’ the four outputs assume the  
values as selected from the inputs. When the OUTPUT EN-  
ABLE input is at a logical ‘‘1’’ the outputs assume logical  
‘‘0’’. The MM54HCT158/MM74HCT158 operates in the  
same manner, except that its outputs are inverted. Select  
decoding is done internally resulting in a single select input  
only. If enabled, the select input determines whether the A  
or B inputs get routed to their corresponding Y outputs.  
Typical propagation delay: 14 ns data to any output
