MICROCIRCUIT DATA SHEET Original Creation Date: 06/28/96 Last Update Date: 03/31/97 Last Major Revision Date: 06/28/96 MN54AC139-X REV 1B0 1-of-4 Decoder/Demultiplexer General Description The AC139 is a high-speed, dual 1-of-4 decoder/demultiplexer. The device has two independent decoders, each accepting two inputs and providing four mutally 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 AC139 can be used as a function generator providing all four minterms of two variables.

The databook specifications should be met, without exception, to ensure that the system design is reliable over its power supply, temperature, and output/input loading variables. National does not recommend operation of FACT TM circuits outside databook specifications.
