N74F258AN PHILIPS [NXP Semiconductors], N74F258AN Datasheet - Page 2

• Manufacturer Part Number: N74F258AN
• Description: Quad 2-line to 1-line selector/multiplexer, inverting 3-State
• Manufacturer: PHILIPS [NXP Semiconductors]

One (1.0) FAST Unit Load is defined as: 20 A in the High state and 0.6mA in the Low state.
FEATURES
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
Select input is Low and the I
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.
