L293B Quad Push-Pull 4-Channel Motor Driver IC (DIP-16)

The L293B is a powerful, high-current quad push-pull driver designed to provide bidirectional drive current for inductive loads such as DC motors, stepper motors, and relays. This monolithic integrated circuit is capable of delivering up to 1A of continuous current per channel, with non-repetitive peak currents reaching 2A. Each pair of drivers is controlled by an inhibit input that can effectively turn off the output transistors, providing a convenient method for motor braking or power saving. To optimize efficiency, the L293B features separate supply pins for the logic and the power stages, ensuring the logic can run at a lower voltage to minimize dissipation. The device is housed in a standard 16-pin DIP package that utilizes the four center pins to conduct heat directly to the printed circuit board, making it a reliable choice for high-performance motor control in industrial and robotic applications.

Key Features:

Peak output current of 2A per channel for non-repetitive surges.

Integrated overtemperature protection to prevent damage from overheating.

Separate logic supply input allows for lower voltage operation and reduced power loss.

Inhibit facility provides an easy way to disable all four output transistors.

High noise immunity with inputs fully compatible with standard TTL logic.
