MC74AC253, MC74ACT253 Dual 4-Input Multiplexer with 3-State Outputs
The MC74AC253/74ACT253 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.

FUNCTIONAL DESCRIPTION The MC74AC253/74ACT253 contains two identical 4-input multiplexers with 3-state outputs. 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) 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.
