PCF8575CDB Frequently Asked Questions (FAQs)

  • The PCF8575CDB can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCF8575CDB has internal pull-up resistors on the I2C bus, but they are not enabled by default. You need to enable them by setting the PU (Pull-up Enable) bit in the Control Register (Register 0x03).
  • The PCF8575CDB's I/O pins can source or sink up to 20 mA of current, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
  • The PCF8575CDB can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state and clear all registers.
  • Yes, the PCF8575CDB can be used as a level translator between 5V and 3.3V or 2.5V systems. However, it is recommended to use an external voltage regulator to ensure that the VCC pin is at the correct voltage level.
