When the enable (EN) input of the D3_8E decoder/demultiplexer is High, one of eight active-High outputs (D7 - D0) is selected with a 3-bit binary address (A2 - A0) input. The non-selected outputs are Low. Also, when the EN input is Low, all outputs are Low. In demultiplexer applications, the EN input is the data input.
