The ULN2803 is a monolithic integrated low-voltage, high-current Darlington array. It contains eight independent Darlington driver circuits with built-in clamp diodes, suitable for driving inductive loads such as relays and stepper motors. By paralleling the Darlington tubes, higher output current capability can be achieved. This circuit is widely applicable in relay driving, lighting driving, display screen driving (LED), stepper motor driving, and logic buffering. Each Darlington tube in the ULN2803 has a 2.7K base resistor in series, allowing direct connection to TTL/CMOS circuits under a 5V operating voltage, capable of directly processing data handled by standard logic buffers.
