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 () inputs, and
complementary OE and
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
