ULN2068B Frequently Asked Questions (FAQ)

  • The ULN2068B can sink up to 500mA per output, but it's recommended to limit it to 350mA for reliable operation.

  • No, the ULN2068B is designed as a low-side switch, meaning it can only sink current to ground. It's not suitable for high-side switching applications.

  • You can add a flyback diode (e.g., 1N4007) in parallel with the inductive load to protect the ULN2068B from back-EMF. The diode should be rated for the maximum voltage and current of the load.

  • The ULN2068B can operate with input voltages as low as 2.7V, but it's recommended to use a minimum of 4.5V for reliable operation.

  • Yes, the ULN2068B can be used to drive a relay, but make sure to check the relay's coil voltage and current requirements to ensure they are within the ULN2068B's specifications.
