(3-State)
FEATURES Multifunction capability Non-inverting data path 3-State outputs See 74F257A for non-inverting version
DESCRIPTIONThe 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.

DC ELECTRICAL CHARACTERISTICS(Over recommended operating free-air temperature range unless otherwise noted.)
NOTES: For conditions shown as MIN or MAX, use the appropriate value specified under recommended operating conditions for the applicable type. All typical values are at VCC = 5V, Tamb = 25°C. Not more than one output should be shorted at a time. For testing IOS, the use of High-speed test apparatus and/or sample-and-hold
techniques are preferable in order to minimize internal heating and more accurately reflect operational values. Otherwise, prolonged shorting
of a High output may raise the chip temperature well above normal and thereby cause invalid readings in other parameter tests. In any
sequence of parameter tests, IOS tests should be performed last.
