Package

The ULN2803APG is typically packaged in a 18-pin DIP (Dual In-line Package) format. It features a compact design suitable for through-hole mounting and is commonly used for driving loads such as relays and motors.

Pinout

The ULN2803APG is an octal high-voltage, high-current Darlington transistor array. It features a total of 18 pins. The pin configuration includes:
1. Inputs (Pins 1-8): These are the input pins (1A to 8A) where control signals are applied. Each input corresponds to a Darlington pair output.
2. Common pin (Pin 9): This is typically connected to the positive voltage supply (V+), which is used for driving loads.
3. Outputs (Pins 10-17): These output pins (1Y to 8Y) connect to the load. When the corresponding input pin is activated, the output pin will turn on and sink current.
4. Pin 18: Ground pin (GND), which is connected to the circuit ground.
The ULN2803APG is commonly used for interfacing low-voltage logic to higher-voltage loads, such as motors, relays, and lamps.
