SN74LS139
Dual 1−of−4 Decoder/ Demultiplexer
The LSTTL/MSI SN74LS139 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 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.
