ULN2003 Seven Darlington Array DIP-16

The ULN2003 Seven Darlington Array (DIP-16) is a versatile and widely used IC designed for driving relays, stepper motors, LEDs, and other high-current loads directly from a microcontroller or logic circuit. It is one of the most popular driver chips in electronics, robotics, and automation.

This IC contains seven Darlington transistor pairs, each capable of sinking up to 500mA per channel with a maximum output voltage of 50V. In addition, it includes built-in flyback diodes for safe operation when driving inductive loads like motors and relays.

Because it uses a standard 16-pin DIP package, it is easy to use on breadboards, PCBs, and prototyping boards. Also, it works perfectly with Arduino, Raspberry Pi, STM32, and other logic-level control systems.
