PCA9548ADWG4 Frequently Asked Questions (FAQs)

  • The PCA9548ADWG4 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 PCA9548ADWG4 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 PCA9548ADWG4 can be used to isolate I2C buses with different clock domains, but you need to ensure that the clock domains are synchronized or use a clock domain crossing circuit to avoid data corruption.
  • The PCA9548ADWG4 can drive I2C buses with capacitance up to 400 pF, but it's recommended to limit the capacitance to 100 pF for reliable operation.
