INTEGRATED CIRCUITS 74F139 Dual 1-of-4 decoder/demultiplexer Product specification IC15 Data Handbook 1990 Feb 23 Philips Semiconductors Philips Semiconductors Product specification 1-of-4 decoder/demultiplexer 74F139 FEATURES • Demultiplexing capability • Two independent 1-of-4 decoders • Multifunction capability 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 (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-of-4 demultiplexer application.
