DM54LS450/DM74LS450 16:1 Multiplexer
General Description
Features/Benefits
Y
24-pin SKINNYDIP saves space
The 16:1 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.
Y
Similar to 74150 (Fat DIP)
Y
Low current PNP inputs reduce loading
