description
This octal buffer or line driver is 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
AC11240 and AC11244, 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. This device features a high
fan-out.
The 54AC11241 is characterized for operation
over the full military temperature range of − 55°C
to 125°C. The 74AC11241 is characterized for
operation from − 40°C to 85°C.
