PCA9544ADWR Frequently Asked Questions (FAQs)

  • The PCA9544ADWR 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 PCA9544ADWR in dual-bus mode, connect the SCL/SDA pins of the two buses to the corresponding pins on the PCA9544ADWR, and use the EN pins to enable or disable each bus. The PCA9544ADWR will automatically switch between the two buses based on the EN pin states.
  • The PCA9544ADWR can drive bus capacitances up to 400 pF, but it's recommended to limit the capacitance to 200 pF for reliable operation.
  • Yes, the PCA9544ADWR can be used to connect multiple masters to a single slave device. The PCA9544ADWR will arbitrate access to the slave device and ensure that only one master can access the slave at a time.
  • The PCA9544ADWR can be reset by pulling the RESET pin low for at least 1 ms. This will reset the device to its default state.
