PCA9543APW,112 Frequently Asked Questions (FAQs)

  • The PCA9543APW,112 can support I2C bus frequencies up to 400 kHz, but it's recommended to limit it to 100 kHz for reliable operation.
  • Yes, the PCA9543APW,112 can be used as a level shifter for I2C signals, but it's not recommended as it's primarily designed as a bus switch. For level shifting, it's better to use a dedicated level shifter IC.
  • To ensure correct switching, make sure to use the enable pins (EN0 and EN1) to control the switching between the two I2C buses. Also, ensure that the voltage levels on the enable pins are within the recommended range.
  • The PCA9543APW,112 can sink or source up to 10 mA of current on the I2C bus, but it's recommended to limit it to 5 mA for reliable operation.
  • No, the PCA9543APW,112 is designed to switch between only two I2C buses. If you need to switch between more than two buses, you'll need to use multiple PCA9543APW,112 devices or a different IC.
