Product overview
Overview
The MC74AC139/74ACT139 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 MC74AC139/74ACT139 can be used as a function generator providing four minterms of two variables.
Features
• Multifunctional Capability
• Two Completely Independent 1−of−4 Decoders
• Active LOW Mutually Exclusive Outputs
• Outputs Source/Sink 24 mA
• ′ACT139 Has TTL Compatible Inputs
•
These are Pb−Free Devices
