74F139
Dual 1-of-4 Decoder/Demultiplexer
General Description
The F139 is a high-speed, dual 1-of-4 decoder/demulti-
plexer. The device has two independent decoders, each
accepting two inputs and providing four mutually exclusive
active LOW outputs. Each decoder has an active LOW
Enable input which can be used as a data input for a 4-out-
put demultiplexer. Each half of the F139 can be used as a
function generator providing all four minterms of two vari-
ables.

Note 1: Absolute maximum ratings are values beyond which the device
may be damaged or have its useful life impaired. Functional operation
under these conditions is not implied.
Note 2: Either voltage limit or current limit is sufficient to protect inputs.
