DESCRIPTION
The 74LV139 is a low-voltage Si-gate CMOS device that is pin and
function compatible with 74HC/HCT139.
The 74LV139 is a dual 2-to-4 line decoder/demultiplexer. This device
has two independent decoders, each accepting two binary weighted
inputs (nA
0
and nA
1
) and providing four mutually exclusive active
LOW outputs (nY
0
to nY
3
). 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.
