topGeneral description
The 74HC/HCT139 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL
(LSTTL). It is specified in compliance with JEDEC standard no. 7A.
The 74HC/HCT139 are high-speed, dual 2-to-4 line decoder/multiplexers. This device has two independent decoders, each
accepting two binary weighted inputs (nA0 and nA1) and providing four mutually exclusive active LOW outputs (nY0 to
nY3). Each decoder has an active LOW enable input (nE).
When nE is HIGH, every output is forced HIGH. The enable can be used as the data input for a 1-to-4 demultiplexer
application.
The '139' is identical to the HEF4556 of the HE4000B family.
