It selects four bits of data from two sources under control of a common Select input (S). When the Select input is LOW, the I 0x 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 74F258A is the logic implementation of a 4-pole, 2- position switch where the position of the switch is deter- mined by the logic levels supplied to the Select input. The logic equation for the outputs is shown below: Z n = OE • (I1n • S + I0n • S) When the Output Enable input (OE) is HIGH, the outputs are forced to a high impedance OFF 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.
