PCA9548ARGER Frequently Asked Questions (FAQs)

  • The PCA9548ARGER 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 PCA9548ARGER for multiple masters, connect the SCL and SDA pins of each master to the corresponding pins on the PCA9548ARGER. Then, use the EN pins to enable or disable each master's access to the bus.
  • The PCA9548ARGER can drive I2C buses with capacitance up to 400 pF. Exceeding this limit may cause signal integrity issues.
  • Yes, the PCA9548ARGER can switch between multiple I2C buses with different voltage levels, but ensure that the voltage levels are within the recommended operating range of 1.65 V to 5.5 V.
  • The PCA9548ARGER can be reset by pulling the RESET pin low for at least 1 ms. This resets the device to its default state.
