FUNCTIONAL DESCRIPTION
The LS42 decoder accepts four active HIGH BCD inputs
and provides ten mutually exclusive active LOW outputs, as
shown by logic symbol or diagram. The active LOW outputs
facilitate addressing other MSI units with LOW input
enables.
The logic design of the LS42 ensures that all outputs
are HIGH when binary codes greater than nine are applied
to the inputs.
The most significant input A
3
produces a useful inhibit
function when the LS42 is used as a one-of-eight decoder.
The A
3
input can also be used as the Data input in an 8-output
demultiplexer application.
