74ACT258 Quad 2-Input Multiplexer with 3-STATE Outputs tm Features General Description ■ ICC and IOZ reduced by 50% ■ Multiplexer expansion by tying outputs together The ACT258 is a quad 2-input multiplexer with 3-STATE outputs. Four bits of data from two sources can be selected using a common data select input. The four outputs present the selected data in the complement (inverted) form. The outputs may be switched to a high impedance state with a HIGH on the common Output Enable (OE) input, allowing the outputs to interface directly with bus-oriented systems. ■ Inverting 3-STATE outputs ■ Outputs source/sink 24mA ■ TTL-compatible inputs Ordering Information Order Number Package Number Package Description 74ACT258SC M16A 16-Lead Small Outline Integrated Circuit (SOIC), JEDEC MS-012, 0.150” Narrow Body 74ACT258SJ M16D 16-Lead Small Outline Package (SOP), EIAJ TYPE 11, 5.3mm Wide 74ACT258MTC MTC16 16-Lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153, 4.4mm Wide Device also available in Tape and Reel.

It selects four bits of data from two sources under control of a common Select input (S). When the Select input is LOW, the I0x inputs are selected and when Select is HIGH, the I1x inputs are selected. The data on the selected inputs appears at the outputs in inverted form. The ACT258 is the logic implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic levels supplied to the Select input. The logic equations for the outputs are shown below: Za = OE • (I1a • S + I0a • S) IEEE/IEC Zb = OE • (I1b • S + I0b • S) Zc = OE • (I1c • S + I0c • S) Zd = OE • (I1d • S + I0d • S) When the Output Enable input (OE) is HIGH, the outputs are forced to a high impedance state. If the outputs of the 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 there is no overlap.
