PCA9548APWRG4 Frequently Asked Questions (FAQs)

  • The PCA9548APWRG4 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 PCA9548APWRG4 can be used as a level shifter for I2C signals, but it's not recommended as it's primarily designed as an I2C bus expander. For level shifting, it's better to use a dedicated level shifter IC.
  • To configure the PCA9548APWRG4 for multiple masters on the I2C bus, you need to use the EN pin to enable or disable the bus expander. You can also use the INT pin to generate an interrupt when a master is detected on the bus.
  • The PCA9548APWRG4 can support up to 8 downstream devices on each of its 8 channels, making it possible to connect up to 64 devices in total.
  • Yes, the PCA9548APWRG4 is compatible with both 3.3V and 5V devices on the same I2C bus, but you need to ensure that the voltage levels are compatible and that the devices can operate at the same frequency.
