PCA9554APW Frequently Asked Questions (FAQs)

  • The PCA9554APW can support I2C bus frequencies up to 400 kHz.
  • The PCA9554APW can be configured for input or output mode by writing to the configuration register (Register 0x06). A '1' in the corresponding bit position sets the pin as an input, while a '0' sets it as an output.
  • The PCA9554APW can sink or source up to 25 mA per pin.
  • The PCA9554APW can be reset by pulling the RESET pin low for at least 1 ms. This resets all registers to their default values.
  • The internal pull-up resistors on the PCA9554APW are used to pull up the I2C bus lines (SCL and SDA) to the supply voltage (VCC) when the device is not actively driving the bus.
