I am not sure what you are looking for. The L 297 is a controller to drive a chip such as the L298 to drive a stepper.
Are you looking for a chip to control an L298 or are you looking for a stepper driver chip.
To drive a L298 with multi steps most people use a small microcontroller.
To drive a stepper with a single chip there are several available but It depends on what power/voltage level you need as well as can you build a board with fine traces or do you require a dip package like the L297
