PCA9555DB Frequently Asked Questions (FAQs)

  • The PCA9555DB can support I2C bus frequencies up to 400 kHz.
  • The PCA9555DB can be reset by pulling the RESET pin low for a minimum of 1 ms. This will reset the device to its default state.
  • The PCA9555DB can sink or source up to 25 mA of current per output pin.
  • Yes, the PCA9555DB can be used as a level translator. It can translate signals from a lower voltage domain to a higher voltage domain, or vice versa.
  • The PCA9555DB can be configured for input or output mode by writing to the configuration register. A '1' in the configuration register sets the pin as an input, while a '0' sets the pin as an output.
