DESCRIPTION
The 74LVC139 is a low-voltage, low-power, high-performance
Si-gate CMOS device, superior to most advanced CMOS
compatible TTL families.
The 74LVC139 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 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.
