This device has two independent decoders, each accepting two binary weighted inputs (A0n, A1n) and providing four mutually exclusive active-Low outputs (Q0n–Q3n).
Each decoder has an active-Low enable (E).
When E is High, every output is forced High.
The enable can be used as the data input for a 1-o...
