HD74HC258
Quad. 2-to-1-line Data Selectors/Multiplexers
(with 3-state outputs)
REJ03D0602–0200
(Previous ADE-205-479)
Rev.2.00

Description
The large output drive capability coupled with the 3-state feature make this device ideal for interfacing with bus lines in
a bus organized system. When the output control input line is taken high, the outputs of all four multiplexers are sent
into a high impedance state. When the output control line is low, the select input chooses whether the A or B input is
used.

2. Waveform– A is for an output with internal conditions such that the
output is low except when disabled by the output control.
3. Waveform– B is for an output with internal conditions such that the
output is high except when disabled by the output control.
4. The output are measured one at a time with one transition per measurement.
