L293D Motor Driver IC (DIP 16, Dual H Bridge)

The L293D is a four channel motor driver IC designed to control DC motors, stepper motors, relays, and other inductive loads. It contains two H bridge driver circuits that allow bidirectional control of two DC motors or control of a bipolar stepper motor. The IC includes internal clamp diodes for inductive load protection and separate logic and motor supply connections.
