These octal buffers/line drivers are designed for 2.7-V to 5.5-V VCC operation.
The 'LV244 are designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The 'LV244 are organized as two 4-bit line drivers with separate output-enable (OE) inputs. When OEis 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 SN74LV244 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.
The SN54LV244 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74LV244 is characterized for operation from -40°C to 85°C.
