PCA9555DBQR Frequently Asked Questions (FAQs)

  • The PCA9555DBQR can support I2C bus frequencies up to 400 kHz.
  • To configure the PCA9555DBQR to operate in input mode, set the corresponding bit in the configuration register (register 0x06) to '1'. This will enable the input mode for the respective pin.
  • The PCA9555DBQR can sink or source up to 25 mA per pin.
  • The PCA9555DBQR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
  • The internal pull-up resistors on the PCA9555DBQR are used to pull up the I2C bus lines (SDA and SCL) to the supply voltage (VCC) when the device is not actively driving the bus.
