ULN2803 -Darlington Transistor Arrays

ULN2803 -Darlington Transistor Arrays

The ULN2803A device is a high-voltage, high-current Darlington transistor array. The device consists of eight NPN Darlington pairs that feature high-voltage outputs with common-cathode clamp diodes for switching inductive loads. The collector-current rating of each Darlington pair is 500 mA. The Darlington pairs may be connected in parallel for higher current capability.


  • 500-mA-Rated Collector Current (Single Output)
  • High-Voltage Outputs: 50 V
  • Output Clamp Diodes
  • Inputs Compatible With Various Types of Logic
  • Relay-Driver Applications

  • Relay Drivers
  • Lamp Drivers 
  • Display Drivers (LED and Gas Discharge)
  • Line Drivers
  • Logic Buffers
