74LVC139
Datasheet
General description
The 74LVC139 is a high-performance, low-voltage and low-power 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 (nA0 and nA1) and providing four mutually exclusive active LOW outputs (nY0 to nY3). 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.
Features
- Wide supply voltage range from 1.2 V to 3.6 V
- Inputs accept voltages up to 5.5 V
- CMOS low power consumption
- Direct interface with TTL levels
- Demultiplexing capability
- Two independent 2-to-4 decoders
- Multifunction capability
- Active LOW mutually exclusive outputs
- Output drive capability 50 Ohm transmission lines at 125 Cel
- In accordance with JEDEC standard no. 8-1A
- ESD protection:
-
HBM EIA/JESD22-A114-A exceeds 2000 V
MM EIA/JESD22-A115-A exceeds 200 V.
