PCA9547PW Frequently Asked Questions (FAQs)

  • The PCA9547PW can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • No, the PCA9547PW 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 pin to enable or disable the switch. Also, ensure that the I2C bus is idle before switching to a new bus.
  • The PCA9547PW can drive I2C buses with capacitance up to 400 pF. Exceeding this limit may affect the signal integrity and reliability of the I2C bus.
  • Yes, the PCA9547PW is suitable for hot-swappable I2C bus applications, as it can detect and recover from bus faults and short circuits. However, ensure that the system is designed to handle the power-on and power-off sequences correctly.
