The ULN2002A is a high-voltage, high-current Darlington transistor array from STMicroelectronics. It features seven independent NPN Darlington pairs, each capable of handling up to 500mA and withstanding a 50V load voltage. The device is configured for low-side switching and operates with an inverting input.
This transistor array is suitable for driving a variety of loads, including relays, solenoids, and stepper motors. Its parallel interface simplifies integration into existing designs. The ULN2002A is housed in a standard 16-DIP through-hole package, making it easy to mount on printed circuit boards.
Key electrical characteristics include a 1:1 input-to-output ratio and a maximum output current of 500mA per channel. The operating temperature range is from -40°C to 85°C, ensuring reliable performance in various environmental conditions. The device does not require a separate supply voltage (Vcc/Vdd) for its internal logic, simplifying power management in applications.
