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 ALS241C, AS240A, and AS241A, 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 SN74ALS244C is identical to the standard version, except that the recommended maximum IOL for the -1 version is 48 mA. There no -1 version of the SN54ALS244C. The SN54ALS244C and SN54AS244A are characterized for operation over the full military temperature range to 125°C. The SN74ALS244C and SN74AS244A are characterized for operation from to 70°C.
