It has seven Darlington Pairs inside, where each can drive loads up to 50V and mA. ULN is also commonly used while driving Stepper Motors. So when the negative terminal of the LED is uln2003n datasheet it completes the circuit and uln2003n datasheet glows. Top menu About Us Contact.

ULN Datasheet(PDF) – STMicroelectronics

Output for 5 th channel. Uln2003n datasheet if you uln2003n datasheet anything that anything more than 5V 80mA to work, uln2003n datasheet this IC would be the right choice for you. Used as test pin or Voltage suppresser vatasheet optional to use. Notice that the Positive pin of the LED is connected to the positive load voltage and the negative pin is connected to the output pin of the IC. These ICs are hln2003n when driving a wide range of loads and are used as relay drivers, display drivers, line drivers etc.

Interface GPS with Arduino.

Respective outputs of seven input pins. Adding to that we can a ground and Common pin. Input 1 to Input 7. It might dtaasheet surprising to note that this IC does not have any Vcc power pin; this is because the power required for the transistors to work will be drawn uln203n the input pin itself. SPI Module of Arduino. Input for 3 rd channel. In the circuit consider the LED to be the loads and the logic pins blue colour as the uln2003n datasheet connected to the Uln2003n datasheet circuit or Microcontroller uln2003n datasheet Arduino.

Output for 4 th channel. Output for 2 nd channel.

It can be used a test switch, meaning when this pin is grounded all the datasneet pins uln2003n datasheet be grounded.

Top menu About Us Advertise. The COM pin is connected to ground through a switch, this connection is optional.

Different versions of this family interface to different logic families. Output for 3 rd channel. Output for 6 th channel.

Output for 1 st channel. Input for 1 st channel.

IC ULN Pin Diagram, Features, Equivalents & Datasheet

Input for 7 th channel. The loads connected to the output pin can be maximum uln2003n datasheet 50C and mA each. Input for 6 th channel. Skip to main content.

Input for 4 th channel. However you can run higher current loads buy combining two or more output pins to gather. Input for 5 th channel. The schematic for each driver is given below: Ground Reference Voltage 0V. Skip to main content. The uln2003n datasheet and outputs are provided opposite to uln2003n datasheet other in the pin layout. Output for 7 th channel. Interface SD Card with Arduino. Each channel or darlington pair in ULN is rated at mA and can uln2003n datasheet peak current of mA.

Complete Technical Details can be found at the datasheet give at the end of this page. The ground uln2003n datasheet, as usual is grounded and the usage of Common pin is optional. Input for 2 nd channel. This is because when the input pin of the Uln2003n datasheet gets high the respective output pin will get connected to ground.

ULN2003 Motor Driver IC

A darlington pair is an arrangement datasheey two bipolar transistors. Output 1 to Output 7. It contains seven open collector darlington uln2003n datasheet with common emitters. Common free wheeling diodes.
