description
These octal buffers and line drivers are designed
specifically to improve the performance and
density of 3-state memory address drivers, clock
drivers,
and
bus-oriented
receivers
and
transmitters by eliminating the need for 3-state
overlap protection. The designer has a choice of
selected
combinations
of
inverting
and
noninverting outputs, symmetrical active-low
output-enable (OE) inputs, and complementary
OE and OE inputs. These devices feature high
fan-out and improved fan-in.
The SN54AS756 is characterized for operation
over the full military temperature range of 55
°C
to 125
°C. The SN74AS756 and SN74AS757 are
characterized for operation from 0
°C to 70°C.
