PCA9546APW Frequently Asked Questions (FAQs)

  • The PCA9546APW 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 PCA9546APW can switch between multiple I2C buses with different voltage levels, but the voltage on the SCL and SDA pins must be within the specified range of 1.8 V to 5.5 V.
  • To ensure correct switching, make sure to follow the recommended switching sequence and timing in the datasheet, and use the EN pin to enable or disable the switch.
  • Yes, the PCA9546APW can be used to isolate I2C buses with different clock domains, but you need to ensure that the clock domains are properly synchronized and that the PCA9546APW is configured correctly to handle the clock domain crossing.
  • The PCA9546APW can drive up to 400 pF of capacitance on the I2C bus, but it's recommended to limit the capacitance to 100 pF for reliable operation.
