PCA9518PW Frequently Asked Questions (FAQs)

  • The PCA9518PW 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 PCA9518PW for bidirectional voltage translation, connect VCC to the higher voltage supply, and VL to the lower voltage supply. Then, connect the I2C bus signals (SCL and SDA) to the corresponding pins on the PCA9518PW.
  • The PCA9518PW can handle a maximum voltage difference of 5.5 V between VCC and VL.
  • Yes, the PCA9518PW can be used for level shifting between 1.8 V and 3.3 V. However, ensure that the input voltage on the VL pin is within the recommended operating range of 1.2 V to 5.5 V.
  • To ensure that the PCA9518PW is powered up correctly, apply power to VCC first, followed by VL. This ensures that the internal voltage regulators are powered up in the correct sequence.
