PCA9546ARGVR Frequently Asked Questions (FAQs)

  • The PCA9546 can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
  • To configure the PCA9546 to work with multiple masters, you need to connect the SCL and SDA lines of each master to the corresponding SCL and SDA lines of the PCA9546. Then, you need to configure the PCA9546 to enable multi-master mode by setting the correct values in the control register.
  • The PCA9546 can drive a maximum capacitance of 400 pF on the bus. Exceeding this limit may affect the reliability of the I2C bus.
  • The PCA9546 can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
  • Yes, the PCA9546 is compatible with both 3.3V and 5V devices. It can translate the voltage levels between the two voltage domains.
