PCA9517DP Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9517DP can support?
  The PCA9517DP can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
• Can PCA9517DP be used as a level shifter for other protocols besides I2C?
  No, PCA9517DP is specifically designed for I2C bus level shifting and is not recommended for use with other protocols like SPI, UART, or GPIO.
• How do I ensure that the PCA9517DP 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 sides of the device are properly biased to the correct voltage levels.
• What is the maximum capacitance that can be driven by the PCA9517DP?
  The PCA9517DP 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 PCA9517DP be used in a hot-swappable application?
  Yes, PCA9517DP is designed to support hot-swapping, but it's essential to ensure that the power supply and biasing are properly managed during the hot-swap event to prevent damage to the device.
