PCF8574ADW Frequently Asked Questions (FAQs)

  • The PCF8574ADW can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • The internal pull-up resistors on the I/O pins are enabled by default. To disable them, set the corresponding bit in the configuration register (address 0x04) to 1. You can also use external pull-up resistors if needed.
  • The PCF8574ADW can sink or source up to 25 mA of current on each I/O pin, but it's recommended to limit it to 10 mA for reliable operation.
  • The PCF8574ADW can be reset by pulling the RESET pin low for at least 1 ms. You can also reset the device by sending a reset command over the I2C bus (address 0x00, data 0x06).
  • The INT pin is an interrupt output that is asserted low when any of the input pins change state. It can be used to wake up a microcontroller from sleep mode or to trigger an interrupt.
