    PCA9555D Frequently Asked Questions (FAQs)

    • The PCA9555D can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz or lower for reliable operation.
    • If the input voltage is higher than 6V, it's recommended to use an external voltage regulator or a voltage divider to bring the voltage within the recommended range. Additionally, ensure that the total current drawn from the device does not exceed the maximum rating.
    • The minimum input voltage required for the PCA9555D to operate correctly is 2.3V. However, it's recommended to operate the device at a minimum of 2.7V to ensure reliable operation.
    • Yes, the PCA9555D can be used as a level shifter for 5V to 3.3V or vice versa. However, ensure that the input voltage and output voltage are within the recommended operating range, and that the total current drawn from the device does not exceed the maximum rating.
    • The PCA9555D can be reset by pulling the RESET pin low for a minimum of 1 ms. This will reset the device to its default state.
