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, thesedevicesprovidethe

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 I for the -1 version is 48 mA. There is

no -1 version of the SN54ALS244C.
