FEATURES
· Multifunction capability · Non-inverting data path · 3-State outputs · See 74F257A for non-inverting version
DESCRIPTION
The 74F258A has four identical 2-input multiplexers with 3-State outputs which select 4 bits of data from two sources under control of a common Select (S) input. The I0n inputs are selected when the Select input is Low and the I1n inputs are selected when the Select input is High. Data appears at the outputs in inverted form. The 74F258A is the logical implementation of a 4-pole, 2-position switch where the position of the switch is determined by the logic level supplied to the Select input. Outputs are forced to a High impedance ``off" state when the Output Enable input (OE) is High. All but one device must be in the High impedance state to avoid currents that would exceed the maximum ratings if outputs are tied together. Design of the output signals must ensure that there is no overlap when outputs of 3-State devices are tied together.
