STMicroelectronics ULN2003 NPN Darlington Array 7 Outputs, 50V 500mA, DIP16

The STMicroelectronics ULN2003 Darlington Array provides seven high-voltage, high-current open collector Darlington pairs with common emitters, making it an ideal solution for demanding switching applications. This versatile driver is specifically engineered to interface between low-level logic and high-power loads, offering robust performance in industrial and electronic control systems.

Each of the seven outputs can drive inductive loads such as relays, stepper motors, and DC brushed motors, thanks to the integrated suppression diodes that safeguard the device from voltage spikes. The outputs can be paralleled to achieve higher current handling, offering design flexibility for heavy-duty applications. Inputs are compatible with TTL, CMOS, PMOS, and DTL logic levels, ensuring seamless integration with a variety of control circuits. The input pins are conveniently placed opposite the output pins, simplifying PCB layout and improving circuit clarity.

This DIP16 packaged IC operates over a wide temperature range up to 85°C and is suitable for through-hole mounting, making it easy to prototype and manufacture. Whether you are driving lamps, LEDs, gas discharge displays, or need a reliable line driver, this Darlington array provides a dependable and cost-effective solution.
