ULN2075B Frequently Asked Questions (FAQs)

  • The ULN2075B can sink up to 350mA per output, but it's recommended to limit it to 250mA for reliable operation.
  • Use a flyback diode (e.g., 1N4007) in parallel with the inductive load to absorb the back-EMF. This prevents voltage spikes from damaging the ULN2075B.
  • The ULN2075B can operate with input voltages as low as 3.5V, but it's recommended to use a minimum of 4.5V for reliable operation.
  • Yes, the ULN2075B can drive a relay, but ensure the relay's coil current is within the ULN2075B's current sinking capability (250mA per output). Also, consider using a relay with a low coil resistance to minimize voltage drop.
  • To minimize power consumption in standby mode, ensure the input voltage is reduced to a minimum (e.g., 3.5V) and the outputs are in a high-impedance state. This can reduce the quiescent current to around 1mA.
