PCA9518PWT Frequently Asked Questions (FAQs)

  • The PCA9518PWT can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
  • No, PCA9518PWT is specifically designed for I2C bus level shifting and is not recommended for use with other communication protocols.
  • To handle hot-swapping or insertion/removal of devices, use the PCA9518PWT's built-in bus-hold feature, which holds the SDA and SCL lines at a valid logic level during power-up or power-down.
  • The PCA9518PWT can drive I2C bus capacitances up to 400 pF, but it's recommended to keep the bus capacitance as low as possible to ensure reliable operation.
  • Yes, PCA9518PWT can be used to level-shift between two I2C buses with different voltage levels, as long as the voltage levels are within the device's specified operating range.
