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
outputs (nY
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.
CL = 50 pF;
VCC = 3.3 V
