54F/74F258A Quad 2-Input Multiplexer with TRI-STATE Outputs November 1994 54F/74F258A Quad 2-Input Multiplexer with TRI-STATE É Outputs General Description The ’F258A is a quad 2-input multiplexer with TRI-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.

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 I 1x inputs are selected. The data on the selected inputs appears at the outputs in inverted form. The ’F258A 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 equation for the outputs is shown below: Z n e OE # (I1n # S a 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 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. Designers should ensure that Output Enable signals to TRI-STATE devices whose outputs are tied together are designed so there is no overlap.
