PCF8575CDBR Frequently Asked Questions (FAQs)

  • The PCF8575CDBR can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz for reliable operation.
  • The internal pull-up resistors on the I2C bus are enabled by default. If you want to use external pull-up resistors, you need to disable the internal pull-ups by setting the corresponding bits in the control register.
  • The PCF8575CDBR can sink or source up to 25 mA of current on each I/O pin, but it's recommended to limit the current to 10 mA to ensure reliable operation.
  • The PCF8575CDBR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
  • Yes, the PCF8575CDBR can be used as a level shifter between 3.3V and 5V logic levels. However, it's recommended to use an external level shifter IC for more reliable operation.
