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 SN54ALS244C, SN54AS244A FK PACKAGE

choice of selected combinations of inverting (TOP VIEW)

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 m A. 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 2Y 2Y

characterized for operation from 0°C to 70°C. 1A
