Pinout

The ULN2803APG is an 8-channel Darlington transistor array with a pin count of 18.

Here's a concise breakdown of its pins:

• Pins 1-8: Input channels (each channel has a base, collector, and emitter)
• Pin 9: VCC (positive supply voltage)
• Pin 10: GND (ground)
• Pins 11-17: Collector outputs
• Pin 18: Common emitter

Each input channel can handle up to 0.5A of current at 50V, making it suitable for driving small motors, solenoids, and other low-voltage loads.

Manufacturer

The manufacturer of the ULN2803APG is Toshiba, a Japanese multinational electronics company that specializes in the production of electronic components, including semiconductors, memory devices, and display panels.
