PCA9518APW Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9518APW can support?
  The PCA9518APW can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
• Can PCA9518APW be used as a level shifter for other protocols besides I2C?
  No, PCA9518APW is specifically designed for I2C bus level shifting and is not recommended for use with other protocols.
• How do I ensure that the PCA9518APW is properly powered and biased?
  Make sure to connect VCC to a stable 3.3V or 5V power supply, and connect GND to a solid ground plane. Also, ensure that the input and output voltage levels are within the recommended operating range.
• What is the maximum capacitance that can be driven by the PCA9518APW?
  The PCA9518APW can drive capacitive loads up to 400 pF, but it's recommended to keep the load capacitance as low as possible to ensure reliable operation.
• Can PCA9518APW be used in a hot-swappable application?
  Yes, PCA9518APW is designed to support hot-swapping, but ensure that the power supply and input/output voltage levels are properly managed during the hot-swap event.
