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
transmitters by eliminating the need for 3-state
overlap protection. With the ′AS756 and
SN74AS757, these devices provide the choice of
selected combinations of inverting outputs,
symmetrical active-low output-enable (OE
)
inputs, and complementary OE and OE
inputs.
The SN54AS760 is characterized for operation
over the full military temperature range of –55°C
to 125°C. The SN74ALS760 and SN74AS760 are
characterized for operation from 0°C to 70°C.
