Product Summary
The 74HC/HCT139 are high-speed Si-gate CMOS devicesand are pin compatible with low power Schottky TTL(LSTTL). It is specified in compliance with JEDECstandard no. 7A.The 74HC/HCT139 are high-speed, dual 2-to-4 linedecoder/multiplexers. This device has two independentdecoders, each accepting two binary weighted inputs(nA0 and nA1) and providing four mutually exclusive activeLOW outputs (nY0 to nY3). Each decoder has an activeLOW enable input (nE).When nE is HIGH, every output is forced HIGH. Theenable can be used as the data input for a 1-to-4demultiplexer application.The “139” is identical to the HEF4556 of the HE4000Bfamily.
Features
(1)Demultiplexing capability; (2)Two independent 2-to-4 decoders; (3)Multifunction capability; (4)Active LOW mutually exclusive outputs; (5)Output capability: standard; (6)ICC category: MSI
