The SN74LV244A octal buffers and line drivers are designed for 2-V to 5.5-V V CC operation.

The SN74LV244A devices are designed specifically to improve both performance and density of the 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. These devices are organized as two 4-bit line drivers with separate output-enable ( OE) inputs.
