Is Now Part of To learn more about ON Semiconductor, please visit our website at www.onsemi.com Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor product management systems do not have the ability to manage part nomenclature that utilizes an underscore (_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please email any questions regarding the system integration to Fairchild_questions@onsemi.com.

74AC139, 74ACT139 Dual 1-of-4 Decoder / Demultiplexer General Description The AC/ACT139 is a high−speed, dual 1−of−4 decoder/demultiplexer. The device has two independent decoders, each accepting two inputs www.onsemi.com 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 AC/ACT139 can be used as a function generator providing all four minterms of two variables.

74AC139, 74ACT139 Logic Symbol/s Functional Description The AC/ACT139 is a high−speed dual 1−of−4 decoder/ demultiplexer. The device has two independent decoders, each of which accepts two binary weighted inputs (A –A ) 0 1 and provides four mutually exclusive active−LOW outputs (O –O ). Each decoder has an active−LOW enable (E). 0 3 When E is HIGH all outputs are forced HIGH. The enable can be used as the data input for a 4−output demultiplexer application. Each half of the AC/ACT139 generates all four minterms of two variables. These four minterms are useful in some applications, replacing multiple gate functions as shown in Figure 1, and thereby reducing the number of packages required in a logic network.
