DESCRIPTION
The 74F139 is a high speed, 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 (Q
Enable (E
). When E is High, every output is forced High. The Enable
can be used as the Data input for a 1-of-4 demultiplexer application.
