PCA9555APW Frequently Asked Questions (FAQs)

  • The PCA9555APW can support I2C bus frequencies up to 400 kHz, but it is recommended to operate at 100 kHz or lower for reliable operation.
  • The PCA9555APW 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 PCA9555APW can sink or source up to 25 mA of current on its GPIO pins, but it is recommended to limit the current to 10 mA or less to ensure reliable operation.
  • Yes, the PCA9555APW can be used as a level translator between 1.8 V and 5 V logic levels. However, it is recommended to use an external voltage regulator to ensure stable voltage levels.
  • The PCA9555APW can be configured for open-drain or push-pull mode by writing to the Configuration Register (Register 0x06). Bit 0 of this register controls the output mode, with 0 being open-drain and 1 being push-pull.
