DM54LS450DM74LS450 161 Multiplexer

General Description

The 161 Mux selects one of sixteen inputs E0 through E15

specified by four binary select inputs A B C and D The

true data is output on Y and the inverted data on W Propa-

gation delays are the same for both inputs and addresses

and are specified for 50 pF loading Outputs conform to the

standard 8 mA LS totem pole drive standard

FeaturesBenefits

Y

24-pin SKINNYDIP saves space

Y

Similar to 74150 (Fat DIP)

Y

Low current PNP inputs reduce loading
