Part Details:

74F139 D April 1988 Revised September 2000 ual 74F139 1-of Dual 1-of-4 Decoder/Demultiplexer -4 Decoder General Description Features The F139 is a high-speed, dual 1-of-4 decoder/demulti- s Multifunction capability plexer. The device has two independent decoders, each s Two completely independent 1-of-4 decoders accepting two inputs and providing four mutually exclusive s Active LOW mutually exclusive outputs active LOW outputs. Each decoder has an active LOW / Enable input which can be used as a data input for a Demult 4-output demultiplexer. Each half of the F139 can be usedas a function generator providing all four minterms of twovariables. iplexer Ordering Code: Order Number Package Number Package Description 74F139SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74F139SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74F139PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Devices also available in Tape and Reel.
