They select two bits from four sources selected by common Select inputs (S 0,S 1). The 4-input mul- tiplexers have individual Output Enable (OE a,O E b) 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 below: Z a e OEa # (I0a # S1 # S0 a I1a # S1 # S0 a I2a # S1 # S0 a I3a # S1 # S0) Zb e OEb # (I0b # S1 # S0 a I1b # S1 # S0 a I2b # S1 # S0 a I3b # S1 # S0) If the outputs of TRI-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. De- signers should ensure that Output Enable signals to TRI- STATE devices whose outputs are tied together are de- signed so that there is no overlap.
