FAST AND LS TTL DATA
DUAL 1-OF-4 DECODER
The MC54/74F139 is a high speed Dual 1-of-4 Decoder/Demultiplexer.
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-output de-
multiplexer. Each half of the F139 can be used as a function generator provid-
ing all four miniterms of two variables.
Multifunction Capability
Two Completely Independent 1-of-4 Decoders
Active Low Mutually Exclusive Outputs
