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 Semiconductors 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.

The device has two independent decoders, each accepting two inputs www.onsemi.com and providing four mutuallyexclusive activeLOW outputs. Each decoder has an activeLOW Enable input which can be used as a data input for a 4output demultiplexer. Each half of the AC/ACT139 can be used as a function generator providing all four minterms of two variables. Features I Reduced by 50% CC Multifunction Capability Two Completely Independent 1of4 Decoders Active LOW Mutually Exclusive Outputs Outputs Source/Sink 24 mA ACT139 has TTLcompatible Inputs ORDERING CODE: Order Number Case Number Package Description 74AC139SC 751BG 16Lead Small Outline Integrated Circuit (SOIC), JEDEC MS012, 0.150 Narrow Body 74AC139SJ 565BF 16Lead Small Outline Package (SOIC), EIAJ Type II, 5.3 mm Wide 74AC139MTC 948AH 16Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO153, 4.4 mm Wide 74AC139PC 648 16Lead Plastic DualInLine Package (PDIP), JEDEC MS001, 0.300 Wide 74ACT139SC 751BG 16Lead Small Outline Integrated Circuit (SOIC), JEDEC MS012, 0.150 Narrow Body 74ACT139SJ 565BF 16Lead Small Outline Package (SOIC), EIAJ Type II, 5.3 mm Wide 74ACT139MTC 948AH 16Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO153, 4.4 mm Wide 74ACT139PC 648 16Lead Plastic DualInLine Package (PDIP), JEDEC MS001, 0.300 Wide NOTE: Device also available in Tape and Reel.
