PCA9546AD Frequently Asked Questions (FAQs)

  • The PCA9546AD can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz to ensure reliable operation.
  • No, the PCA9546AD is designed to switch between multiple I2C buses, not multiple I2C masters. It's intended to allow a single I2C master to access multiple I2C buses.
  • To ensure correct switching, make sure to follow the recommended switching sequence in the datasheet, and use the EN (enable) pin to disable the switch during power-up and power-down to prevent bus contention.
  • The PCA9546AD can drive I2C buses with capacitance up to 400 pF, but it's recommended to keep the bus capacitance as low as possible to ensure reliable operation.
  • No, the PCA9546AD is not designed to switch between I2C buses with different voltage levels. It's intended to operate within a single voltage domain.
