SN54/74LS251  
8-INPUT MULTIPLEXER  
WITH 3-STATE OUTPUTS  
The TTL/MSI SN74LS251 is a high speed 8-Input Digital Multiplexer. It  
provides, in one package, the ability to select one bit of data from up to eight  
sources. The LS251 can be used as a universal function generator to  
generate any logic function of four variables. Both assertion and negation  
outputs are provided.
