The ULN2803C device is a 50V, 500mA 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 500mA. The Darlington pairscan be connected in parallel for higher current capability. Ap.
• 500mA-rated collector current (single output)
• High-voltage outputs: 50V
• Output clamp diodes
• Inputs compatible with various types of logic
2 Applications
• Factory automation and control
• Building automation
• Appliances
• IP network camera
• HVAC valve and actuator control
• Relay, solenoid, and lamp driving
• Stepper motor driving
