DESCRIPTION
The 74ALS139 is a dual 1-of-4 decoder/demultiplexer. 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...
