54157/DM54157/DM74157  
Quad 2-Line to 1-Line Data Selectors/Multiplexers  
General Description  
Features  
Y
Buffered inputs and outputs  
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.  
Y
Typical propagation time 9 ns  
Y
Typical power dissipation 150 mW  
Y
Alternate Military/Aerospace device (54157) is avail-  
able. Contact a National Semiconductor Sales Office/  
Distributor for specifications.  
Applications  
Y
Expand any data input point  
Y
Multiplex dual data buses  
Y
Generate four functions of two variables (one variable  
is common)  
Y
Source programmable counters
