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. With the
′ALS240A, ′ALS241C,
′AS240A, and ′AS241A, 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 -1 version of SN74ALS244C is identical to the
standard version, except that the recommended
maximum IOL for the -1 version is 48 mA. There is
no -1 version of the SN54ALS244C.
The
SN54ALS244C
and
SN54AS244A
are
characterized for operation over the full military
temperature range of – 55
°C to 125°C. The
SN74ALS244C
and
SN74AS244A
are
characterized for operation from 0
°C to 70°C.
