Description
The HD74AC139/HD74ACT139 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 HD74AC139/HD74ACT139 can be used as a function generator providing all four minterms of two variables.

 

Features
• Multifunction Capability
• Two Completely Independent 1-of-4 Decoders
• Active Low Mutually Exclusive Outputs
• Outputs Source/Sink 24 mA
• HD74ACT139 has TTL-Compatible Inputs
