      These octal buffers and line drivers of the SN74F244 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 F240 andF241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs, and complementary OE and OE inputs.

      The SN74F244 is organized as two 4-bit buffers/line drivers with separate output enable (OE) inputs. When OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the high-impedance state.

      The SN74F244 is available in TI!fls shrin small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.

      The SN74F244 is characterized for operation ove the full military temperature range of -55 to125. The SN74F244 is characterized fo operation from 0 to 70.
