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.

• Schottky Process for High Speed

• Multifunction Capability

• Two Completely Independent 1-of-4 Decoders

• Active Low Mutually Exclusive Outputs

• Input Clamp Diodes Limit High Speed Termination Effects

• ESD > 3500 Volts
