Texas Instruments 7-Channel NPN Darlington Transistor Array, 500 mA 50 V, Through Hole, 16-Pin PDIP ULN2003AN

Texas Instruments ULN2003AN is a seven-channel NPN Darlington transistor array designed for high-reliability switching and driver applications. Featuring a robust 16-pin PDIP through hole package, this component is well-suited for electronic circuits requiring multiple high-current outputs within a compact footprint.

With each channel supporting a maximum continuous collector current of 500 mA and a collector-emitter voltage of up to 50 V, the ULN2003AN provides exceptional flexibility for controlling a wide variety of loads. It is constructed with high-voltage, high-current NPN Darlington pairs, which makes it ideal for driving relays, stepper motors, lamps, solenoids, and logic interface circuits in industrial and commercial systems.

Provides seven individual high-voltage Darlington pairs in a single device, streamlining multi-load control. Delivers reliable performance in ambient temperatures from -20°C to 70°C, making it suitable for challenging environments.

Features a low collector-emitter saturation voltage, ensuring efficient operation with reduced power loss. Standard through hole PDIP-16 mounting for broad compatibility with PCBs and prototyping environments. Integrated input resistors accommodate TTL and CMOS logic levels for convenient interfacing.

Each channel is capable of up to 500 mA collector current, supporting moderate to heavy loads. Protective diodes included for handling inductive load switching, ensuring component longevity. Commonly used in industrial automation, control systems, instrumentation, robotics, and consumer electronics.

The Texas Instruments ULN2003AN offers practical advantages in system design, allowing engineers to consolidate multiple power drivers on a single chip. Its rugged construction, wide operating voltage, and strong current-carrying capacity make it a go-to choice for switching and driving tasks. Typical uses include signal interfacing between logic-level outputs and higher-current relays, small motors, and LED matrix displays.

This product is essential in the fields of industrial automation, manufacturing equipment, laboratory instruments, and electronic control panels, where reliable and robust switching is required.
