PCA9546APWT Frequently Asked Questions (FAQs)

  • The PCA9546APWT 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 PCA9546APWT can switch between multiple I2C buses with different voltage levels, but the voltage on each bus must be within the recommended operating range of 1.65 V to 5.5 V.
  • To ensure correct switching, make sure to use the correct control signals (A0, A1, and EN) to select the desired bus, and ensure that the I2C bus is idle before switching to a new bus.
  • The PCA9546APWT can drive I2C buses with capacitance up to 400 pF, but it's recommended to limit the capacitance to 200 pF for reliable operation.
  • Yes, the PCA9546APWT can switch between I2C buses with different clock frequencies, but the clock frequency of each bus must be within the recommended operating range of 10 kHz to 400 kHz.
