ULN2003 IC

ULN2003 IC

Overview:

• Popular Darlington IC with seven Darlington pairs.
• Each pair consists of 1 input and 1 output pin, totaling 7 input and 7 output pins.
• Each pair rated for 50V and 500mA; input pins can be triggered by +5V.

Applications:

• Commonly used to drive large loads with microcontrollers.
• Suitable for:
  • Driving high-power LED arrays.
  • Driving motors in both directions.
  • Controlling stepper motors.
  • Interfacing between low-level logic circuitry and peripheral power loads.
  • Handling interface needs beyond standard logic buffers.
  • Typical loads include relays, solenoids, stepping motors, magnetic print hammers, multiplexed LED and incandescent displays, and heaters.
• Features open-collector outputs with integral clamp diodes.
