PCA9543APWRG4 Frequently Asked Questions (FAQs)

  • The PCA9543APWRG4 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 PCA9543APWRG4 can be used as a level shifter for I2C signals, but it's not recommended as it's primarily designed as a bus expander. For level shifting, it's better to use a dedicated level shifter like the TXS0108.
  • To configure the PCA9543APWRG4 for use with multiple masters, 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 trying to access the bus.
  • The PCA9543APWRG4 can support up to 8 downstream devices on each of its 4 channels, making a total of 32 devices that can be connected.
  • Yes, the PCA9543APWRG4 is 5V tolerant, but it's recommended to use it with 3.3V devices for reliable operation. If you need to use it with 5V devices, ensure that the voltage levels are within the recommended specifications.
