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°C to 85°C.
