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.
