74AC253 • 74ACT253 Dual 4-Input Multiplexer with 3-STATE Outputs November 1988 Revised October 2000 74AC253 74ACT253 Dual 4-Input Multiplexer with 3-STATE Outputs General Description Features The AC/ACT253 is a dual 4-input multiplexer with 3-STATEI and I reduced by 50% CC OZ outputs. It can select two bits of data from four sources Multifunction capability using common select inputs. The outputs may be individu- Non inverting 3-STATE outputs ally switched to a high impedance state with a HIGH on the Outputs source/sink 24 mA respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems.ACT253 has TTL-compatible inputs Ordering Code: Order Number Package Number Package Description 74AC253SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74AC253SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74AC253PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide 74ACT253SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150 Narrow 74ACT253SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE II, 5.3mm Wide 74ACT253MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide 74ACT253PC N16E 16-Lead Plastic Dual-In-Line Package (PDIP), JEDEC MS-001, 0.300 Wide Device also available Tape and Reel.
