ULN2003 Darlington Array IC

Description

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. Key Features: Model: ULN2003A Seven Darlington Array Package Type: DIP-16 7 channels, each up to 500mA output current Maximum output voltage: 50V Built-in flyback diodes for inductive load protection Compatible with TTL and CMOS logic Ideal for driving relays, stepper motors, LEDs, and solenoids Works with Arduino, Raspberry Pi, and microcontroller circuits Perfect for students, hobbyists, and engineers, the ULN2003 Seven Darlington Array DIP-16 is the ideal choice for safe, efficient, and reliable high-current load control.
