PCA9548APW Frequently Asked Questions (FAQs)

  • The PCA9548APW 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 PCA9548APW 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, the PCA9548APW requires a specific sequence of control signals on the SCL and SDA pins. Refer to the datasheet for the recommended switching sequence.
  • The PCA9548APW can drive up to 400 pF of capacitance on the I2C bus, but it's recommended to limit the capacitance to 200 pF for reliable operation.
  • Yes, the PCA9548APW is suitable for hot-swappable I2C bus applications, but it's essential to ensure that the power supply to the device is stable and within the recommended operating range during the hot-swap process.
