DM54LS453/DM74LS453
Quad 4:1 Multiplexer
General Description
The quad 4:1 Mux selects one of four inputs, co through C3,
specified by two binary select inputs, A and B. The true data
is output on Y. Propagation delays are the same for inputs
and addresses and are specified for 50 pF loading. Outputs
conform to the standard 8 mA LS totem pole drive standard.
Features/Benefits
a 24-pin SKINNYDIP saves space
a Twice the density of 74LS153
In Low current PNP inputs reduce loading
