Working Principles

The NLV74HC139ADTR2G is a decoder/demultiplexer IC that takes two address inputs (A0 and A1) and two enable inputs (E1 and E2). Based on the combination of these inputs, the IC activates one of the output lines (Y0-Y7) while keeping the others inactive. The outputs can also be used as demultiplexers by activating the enable inputs accordingly.

Detailed Application Field Plans
