74AC253, 74ACT253 Dual 4-Input Multiplexer with 3-STATE Outputs tm Features General Description ■ ICC and IOZ reduced by 50% ■ Multifunction capability The AC/ACT253 is a dual 4-input multiplexer with 3-STATE outputs. It can select two bits of data from four sources using common select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus oriented systems. ■ Non inverting 3-STATE outputs ■ Outputs source/sink 24mA ■ ACT253 has TTL-compatible inputs Ordering Information 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 Device also available Tape and Reel.

They select two bits from four sources selected by common Select inputs (S0, S1). The 4-input multiplexers have individual Output Enable (OEa, OEb) inputs which, when HIGH, force the outputs to a high impedance (High Z) state. This device is the logic implementation of a 2-pole, 4-position switch, where the position of the switch is determined by the logic levels supplied to the two select inputs. The logic equations for the outputs are shown: Za = OEa • (I0a • S1 • S0 + I1a • S1 • S0 + I2a • S1 • S0 + I3a • S1 • S0) IEEE/IEC Zb = OEb • (I0b • S1 • S0 + I1b • S1 • S0 + I2b • S1 • S0 + I3b • S1 • S0) If the outputs of 3-STATE devices are tied together, all but one device must be in the high impedance state to avoid high currents that would exceed the maximum ratings. Designers should ensure that Output Enable signals to 3-STATE devices whose outputs are tied together are designed so that there is no overlap.
