Darlington array IC HGSEMI ULN2003AMT TR designed for high current and voltage switching applications

Product Overview

The ULN2003A is a high-voltage, high-current Darlington array integrated circuit, comprising seven NPN Darlington pairs. Each unit features an open-collector output and a 2.7K base resistor, ensuring direct compatibility with TTL and 5V CMOS logic levels. This device is designed for high-voltage operation and substantial current handling, capable of sinking up to 500mA per channel and withstanding 50V in the off-state. Its parallel output capability makes it an ideal solution for driving multiple interfaces, including relays, DC lighting, stepper motors, solenoids, and brushless DC motors.
