TECHNICAL DATA
IN74LV139
Dual 2-to-4 line
decoder/demultiplexer; inverting
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.
•

This device contains protection circuitry to guard against damage due to high static voltages or electric
fields. However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages
to this high-impedance circuit. For proper operation, V
IN
and V
OUT
should be constrained to the range GND≤(V
IN
or
V
OUT
)≤V
CC
.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or V
CC
). Unused
outputs must be left open.
