ULN2066B Frequently Asked Questions (FAQs)

  • The maximum current that each output can handle is 500mA, but it's recommended to keep it below 350mA for reliable operation.
  • You can add a flyback diode (e.g., 1N4007) in parallel with the inductive load to protect the ULN2066B from back-EMF.
  • The minimum input voltage required is 3.5V, but it's recommended to use a minimum of 4.5V for reliable operation.
  • Yes, the ULN2066B can be used to drive a relay, but make sure to choose a relay with a coil voltage and current rating that matches the ULN2066B's output capabilities.
  • You can calculate the power dissipation using the formula: Pd = (Vin - Vout) x Iout, where Vin is the input voltage, Vout is the output voltage, and Iout is the output current.
