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.
