PIN FUNCTIONS - L297/1 - L297D (continued) CIRCUIT OPERATION The L297 is intended for use with a dual bridge driver, quad darlington array or discrete power devices in step motor driving applications. It re-ceives step clock, direction and mode signals from the systems controller (usually a microcomputer chip) and generates control signals for ...
The L297 is made with STMicroelectronics’ analog/digital compatible I 2L technology (like Zodiac) and is assem-bled in a 20-pin plastic DIP. A 5V supply is used and all signal lines are TTL/CMOS compatible or open collector transistors. High density is one of the key features of the technology so the L297 die is very compact.

L297 - Stepper Motor Controller - STMicroelectronics
The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer-controlled applications. The motor can be driven in half step, normal and wawe drive modes and on-chip PWM chopper circuits permit switch-mode control of the current in the windings.
