PCF8575PWE4 Frequently Asked Questions (FAQs)

  • The PCF8575PWE4 can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • Yes, the PCF8575PWE4 can be used as a level shifter for I2C signals, as it can translate between 3.3V and 5V logic levels.
  • The internal pull-up resistors on the I2C bus can be disabled by connecting the PU pin to GND. If you want to use external pull-up resistors, connect the PU pin to VCC.
  • The PCF8575PWE4 can source or sink up to 25 mA of current per I/O pin, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
  • Yes, the PCF8575PWE4 can be used in a multi-master I2C bus configuration, but it requires careful design and consideration of bus arbitration and collision detection.
