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 I
0n
inputs are selected when the
Select input is Low and the I
1n
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.
