description
These octal buffers and line drivers are designed
specifically to improve both the performance and
density of 3-state memory address drivers, clock
drivers, and bus-oriented receivers and transmit-
ters. Taken together with the ’ALS241 and ’AS241,
the designer has a choice of selected combina-
tions of inverting and noninverting outputs,
symmetrically G (active-low output control) inputs,
and complementary G and G inputs. These
devices feature high fan-out and improved fan-in.
The SN54’ family is characterized for operation
over the full military temperature range of – 55
°C
to 125
°C. The SN74’ family is characterized for
operation from 0
°C to 70°C.
