description
These octal buffers or line drivers are designed
specifically to improve both the performance and
density of three-state memory address drivers,
clock drivers, and bus-oriented receivers and
transmitters. Taken together with the ACT11240
and ACT11244, these devices provide the choice
of selected combinations of inverting and
noninverting outputs, symmetrical G (active-low
output control) inputs, and complementary G and
G inputs. These devices feature high fan-out.
The 54ACT11241 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The 74ACT11241 is characterized for
operation from − 40°C to 85°C.
