When the enable (EN) input of the D4_16E decoder/demultiplexer is High, one of 16 active-High outputs (D15 - D0) is selected with a 4-bit binary address (A3 - 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.
Refer to the D3_8E section for a representative truth table derivation.
