Description
General part information
SN74F244 Series
These 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 ´F240 and ´F241, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical(active-low output-enable) inputs, and complementary OE andinputs.
The ´F244 is organized as two 4-bit buffers/line drivers with separate output enable () inputs. Whenis low, the device passes data from the A inputs to the Y outputs. Whenis high, the outputs are in the high-impedance state.
The SN74F244 is available in TI's shrink 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.
