PCA9546APWR Frequently Asked Questions (FAQs)

  • The PCA9546APWR can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
  • Yes, the PCA9546APWR can switch between multiple I2C buses with different voltage levels, but the voltage on each bus must be within the recommended operating range of 1.65 V to 5.5 V.
  • To ensure correct switching, make sure to use the correct control signals (SCL0, SCL1, SDA0, SDA1) and follow the recommended switching sequence outlined in the datasheet.
  • The PCA9546APWR can sink or source up to 10 mA of current on the I2C bus, but it's recommended to limit the current to 5 mA for reliable operation.
  • Yes, the PCA9546APWR is designed to support hot-swappable applications, but make sure to follow proper power sequencing and signal routing to avoid bus contention and damage to the device.
