Pinout
Here is a concise overview of its pin functions:
1. Pins 1-7: Inputs for the seven Darlington pairs (IN1 to IN7). Connect these pins to the signal sources you want to control.
2. Pins 8: Ground (GND) pin, which is the common ground for all the Darlington pairs in the IC.
3. Pins 9-15: Corresponding outputs for the seven Darlington pairs (OUT1 to OUT7). Connect these to the loads you intend to drive.
4. Pin 16: Common free-wheeling diode cathode (COM), typically connected to a higher voltage supply to provide a path for inductive kickback protection when driving inductive loads like motors or relays.
The ULN2003AFWG is commonly used for driving relays, lamps, and stepper motors due to its ability to handle higher currents and voltages efficiently.
