About ULN2003 Array IC

The ULN2003 is a versatile Darlington transistor array IC designed for interfacing low-current logic signals with high-voltage, high-current loads. It consists of seven independent NPN Darlington pairs, each capable of driving up to 500mA (600mA peak) with a breakdown voltage of 50V. Each input includes a built-in 2.7kΩ series resistor, making it directly compatible with 5V TTL and CMOS logic levels without external components. The outputs are open-collector, equipped with integrated suppression diodes for driving inductive loads like relays and motors safely. This IC is widely used in microcontroller projects for controlling stepper motors, solenoids, relays, and LED arrays. It is available in a standard 16-pin DIP package for easy breadboarding and prototyping. Choose the ULN2003 for reliable, efficient high-current switching in your electronic designs.
