74AC251 Datasheet | Fairchild Semiconductor

Description The AC/ACT251 is a high-speed 8-input digital multiplexer. It provides, in one package, the ability to select one bit of data from up to eight sources. It can be used as universal function generator to generate any logic function of four variables. Both true and plementary outputs are provided. Features s ICC reduced by 50% s Multifunctional capability s On-chip select logic decoding s Inverting and noninverting 3-STATE outputs s Outputs source/sink 24 m A s ACT251 has TTL-patible inputs Ordering Code: Order Number 74AC251SC 74AC251SJ 74AC251MTC 74AC251PC 74ACT251SC 74ACT251MTC 74ACT251PC Package Number M16A M16D MTC16 N16E M16A MTC16 N16E Package Description 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow Body 16-Lead Small Outline Package (SOP), 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 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 Device also available in Tape and Reel.
