The Texas Instruments SN754410NE is a quadruple half-H driver that can be used for bidirectional control of two DC motors or to control a single stepper motor. This driver chip is the same device that we use in our dual serial motor controller. You can use this item as a replacement part, to stack on an existing motor controller, or to make your own motor or other high-current device controller.
This integrated motor driver has the same pinout as the L293 that is popular in robotics applications, and the SN754410NE has the additional benefits of built-in protection diodes across the power transistors and output current capability of 1 A per driver. For even higher current applications, it is possible to physically stack two devices on top of each other to get almost 2 A of drive current, or you can consider using the L298N dual full-bridge motor driver, which can deliver 2 A per channel and has the same interface as the SN754410NE.
Note: This chip requires additional circuitry to work and it is shipped without documentation. You can find the datasheet under the resources tab.
