Output for 6 th channel. Skip to main content. Complete Technical Details can be found at the datasheet uln2003n datasheet at the end of datashest page.

ULNN Datasheet, PDF – Datasheet Search Engine

Input for 6 th channel. SPI Module of Arduino. Interface GPS with Arduino.

This is because when the input uln2003n datasheet of the IC gets high the respective output pin will get connected to ground. Uln2003n datasheet when the negative terminal of the LED is grounded it completes the circuit and thus glows.


Different versions of this family interface to different logic families. The COM pin is connected to ground through a switch, this connection is optional. It might be surprising to note that this IC does uln2003n datasheet have any Vcc power pin; this is because uln2003n datasheet power required for the transistors to work will be drawn from the input pin itself.

Output for 2 nd channel. ULN is also commonly uln2003n datasheet while driving Stepper Motors. These ICs are used when driving a wide range of loads and are eatasheet as relay drivers, display drivers, line drivers etc. Common free wheeling diodes.

Output for 4 th channel. Skip to main content.

ULN Stepper Motor Driver – Elecrow

The schematic for each uln2003n datasheet is uln2003n datasheet below: The ground pin, as usual is grounded and the usage of Common pin is optional. Top menu About Us Advertise. Adding to that we can a ground and Common pin. Input for 5 th channel.

Input for 2 nd channel. In the circuit consider the LED to be the loads and the logic pins blue colour as the pins connected to the Digital circuit uln2003n datasheet Microcontroller like Arduino. Output 1 to Output 7. Input for 7 uln2003n datasheet channel.


Input for 4 th channel. Uln2003n datasheet can be used a test switch, meaning when this pin is grounded all the output pins will be grounded. Used as test pin or Voltage suppresser pin optional to use.

ULN2003 Motor Driver IC

Input for 3 rd channel. It contains seven open collector darlington pairs with common emitters. Input 1 to Input 7. However you can run higher current loads buy combining two or more output pins to uln2003n datasheet. Notice that the Positive pin of the LED is connected to the positive load voltage and the negative pin uln2003n datasheet connected to the output pin datazheet the IC.

Output for 3 rd channel. Uln2003n datasheet darlington pair is an arrangement of two bipolar transistors.
