Rev. 5 — 19 October 2011
Product data sheet
1. General description
The 74LVC139 is a dual 2-to-4 line decoder/demultiplexer. It has two independent
decoders, each accepting two binary weighted inputs (nA0 and nA1) and providing four
mutually exclusive outputs (nY0 to nY3) that are LOW when selected. Each decoder has
an active LOW input (nE). When nE is HIGH, every output is forced HIGH. The enable
input can be used as the data input for a 1-to-4 demultiplexer application.
