description
This device is designed to multiplex signals from
4-bit data sources to 4-output data lines in
bus-organized systems. The 3-state outputs will
not load the data lines when the output control pin
(G) is at a high logic level.
The 74AC11258 is characterized for operation
from 40

Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only and
functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
