SN754410 Motor Driver IC

This TI SN754410 motor driver features two H-bridges that can be used
for bidirectional control of two DC motors or to control a single
stepper motor. It operates from 4.5 to 36 V and can deliver a peak
current of 1 A per channel (the continuous current you can deliver
depends on how well you can keep the driver IC cool).

The SN754410NE from Texas Instruments is a quadruple half-H driver that can be used for bidirectional control of two DC motors or to control a single bipolar stepper motor.
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, though we recommend you
use a higher power driver in those cases, such as our DRV8835 dual motor driver carrier or DRV8833 dual motor driver carrier.
