General Description
The ’F251Aisa high-speed 8-input digital multiplexer.Itpro-
vides,in one package,the abilityto select onebitof data
fromupto eight sources.Itcanbe usedasa universal func-
tion generatorto generateany logic functionof four vari-
ables. Both assertionand negation outputsare provided.
Features Multifunctional capability On-chip select logic decoding Invertingand non-inverting TRI-STATE outputs
