PCA9546ADGVR Frequently Asked Questions (FAQs)

  • The PCA9546ADGVR 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 PCA9546ADGVR 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 1.65 V to 5.5 V.
  • To ensure correct switching, the control signals (A0, A1, and EN) must be driven by a logic level that is compatible with the VCC supply voltage of the PCA9546ADGVR. Additionally, the control signals must be stable before the I2C bus is accessed.
  • The PCA9546ADGVR can drive a maximum capacitance of 400 pF on the I2C bus. Exceeding this limit may cause signal distortion and affect the reliability of the I2C bus.
  • Yes, the PCA9546ADGVR can be used in a hot-swappable I2C bus application, but it's essential to ensure that the power supply to the device is stable and that the control signals are properly driven during the hot-swap event.
