Description

These  SN74ALS244B octal buffers and line drivers are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Taken together with the 'ALS240A, 'ALS241A, 'AS240, and 'AS241, these devices provide the choice of selected combinations of inverting outputs, symmetrical G (active-low input control) inputs, and complementary G and G inputs.

The 1 version of the SN74ALS244B is identical to the standard version except that the recommended maximum IOL is increased to 48 mA. There is no 1 version of the SN54ALS244B.The SN54ALS244B and SN54AS244 are characterized for operation over the full military temperature range of 55°C to 125°C. The SN74ALS244B and SN74AS244 are characterized for operation from 0°C to 70°C.
