74AC139 74ACT139 Dual 1-of-4 Decoder/Demultiplexer November 1988 Revised November 1999 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 and providing four mutuallyexclusive 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. Features s ICC reduced by 50% s Multifunction capability s Two completely independent 1-of-4 decoders s Active LOW mutually exclusive outputs s Outputs source/sink 24 mA s ACT139 has TTL-compatible inputs Ordering Code: Order Number 74AC139SC 74AC139SJ 74AC139MTC 74AC139PC 74ACT139SC 74ACT139SJ 74ACT139MTC 74ACT139PC Package Number M16A M16D MTC16 N16E M16A M16D MTC16 N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow Body 16-Lead Small Outline Package (SOIC), EIAJ Type II, 5.3mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300” Wide 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow Body 16-Lead Small Outline Package (SOIC), EIAJ Type II, 5.3mm Wide 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 16-Lead Plastic Du……
