C 1995 National Semiconductor Corporation
DM54LS450 DM74LS450 16 1 Multiplexer
General Description
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
