The IN74LV139 is a low-voltage Si-gate CMOS device and is pin
and function compatible with 74HCT139.
The74LV139 is dual 2-to-4 line decoder/demultiplexer . This device
has two independent decoders, each accepting two binary weighted
inputs (A0a,A0b and A1a,A1b) 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.
• Optimized for Low Voltage applications:1.2 to 3.6 V
• Demultiplexing capability
• Two independent 2-to-4 decoders
• Multifunction capability
• Active LOW mutually exclusive outputs
• Output capability: standard
