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 4ALS240A, 4ALS241C,
4AS240A, and 4AS241A, 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.
