Product Summary
The SNJ54HC244J is an Octal buffer and line driver with 3-state outputs. The SNJ54HC244J is designed specifically to improve both the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The SNJ54HC244J is organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs.
