•
Multifunction capability
DESCRIPTION
The 74F139 is a high speed, dual 1-of-4 decoder/demultiplexer. This
device has two independent decoders, each accepting two binary
weighted inputs (A0n, A1n) and providing four mutually exclusive
active-Low outputs (Q0n–Q3n). Each decoder has an active-Low
Enable (E). When E is High, every output is forced High. The Enable
can be used as the Data input for a 1-of-4 demultiplexer application.

NOTES:
1. For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type.
2. All typical values are at V
CC
= 5V, T
amb
= 25°C.
3. Not more than one output should be shorted at a time. For testing I
OS
, the use of high-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, I
OS
tests should be performed last.
