PCA9517D Frequently Asked Questions (FAQs)

  • The PCA9517D can support I2C bus frequencies up to 400 kHz, but it's recommended to operate at 100 kHz or lower for reliable operation.
  • To configure the PCA9517D for bidirectional voltage translation, connect the VCC pin to the higher voltage supply, and the VREF pin to the lower voltage supply. Then, connect the SCL/SDA pins to the corresponding I2C bus signals.
  • The PCA9517D can handle a maximum voltage difference of 5.5V between the VCC and VREF pins.
  • Yes, the PCA9517D can be used for level shifting between 1.8V and 3.3V. However, ensure that the VCC pin is connected to the 3.3V supply and the VREF pin is connected to the 1.8V supply.
  • To prevent oscillation or malfunction due to capacitive loading, ensure that the PCB layout is designed to minimize capacitive loading on the SCL/SDA lines. Additionally, add a 1-10 nF capacitor between the VCC and GND pins to filter out noise.
