The ’AC/’ACT251 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. It can be used as universal  
function generator to generate any logic function of four  
variables. Both true and complementary outputs are provid-  
ed.
