DM74LS157 • DM74LS158  
Quad 2-Line to 1-Line Data Selectors/Multiplexers  
General Description  
Applications  
These data selectors/multiplexers contain inverters and  
drivers to supply full on-chip data selection to the four out-  
put gates. A separate strobe input is provided. A 4-bit word  
is selected from one of two sources and is routed to the  
four outputs. The DM74LS157 presents true data whereas  
the DM74LS158 presents inverted data to minimize propa-  
gation delay time.  
Expand any data input point  
Multiplex dual data buses  
Generate four functions of two variables  
(one variable is common)  
Source programmable counters  
Features  
Buffered inputs and outputs
