PCF8574DWRG4 Frequently Asked Questions (FAQs)

  • The PCF8574 can handle I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • Yes, the PCF8574 can be used as a level shifter between 3.3V and 5V systems, but make sure to follow the recommended voltage levels and current limitations.
  • The internal pull-up resistors on the I2C bus are typically around 10 kΩ. You can add external pull-up resistors if needed, but make sure to calculate the total resistance to avoid overloading the bus.
  • The maximum current that can be sourced or sunk by the PCF8574's I/O pins is around 25 mA per pin, but it's recommended to limit it to 10 mA per pin for reliable operation.
  • No, the PCF8574 is not designed to drive inductive loads like relays or solenoids. It's recommended to use an external driver or buffer for such applications.
