The ULN2803 is a monolithic integrated high-voltage, high-current Darlington array. It internally contains eight independent Darlington driver circuits, each with a clamp diode for driving inductive loads such as relays and stepping motors. By paralleling the Darlington transistors, higher output current capability can be achieved. This circuit is widely applicable in relay driving, lighting driving, display screen driving (LED), stepping motor driving, and as logic buffers. Each Darlington driver in the ULN2803 has a 2.7K base resistor, allowing direct connection to TTL/CMOS circuits at a 5V operating voltage, enabling it to directly process data handled by standard logic buffers.
