SN74LS139
Dual 1-of-4 Decoder/
Demultiplexer
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 demultiplexer. Each
half of the LS139 can be used as a function generator providing all
four minterms of two variables. The LS139 is fabricated with the
Schottky barrier diode process for high speed and is completely
compatible with all ON Semiconductor TTL families.
