PCA9518DBQR Frequently Asked Questions (FAQs)

  • The PCA9518DBQR can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
  • To configure the PCA9518DBQR 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 PCA9518DBQR can sink or source up to 20 mA of current on the I2C bus, making it suitable for driving long cables or multiple devices.
  • To ensure reliable operation in a noisy environment, use a bypass capacitor (e.g., 0.1 uF) between the VCC and GND pins, and consider adding a series resistor (e.g., 1 kΩ) on the SCL and SDA lines to reduce noise coupling.
  • Yes, the PCA9518DBQR can be used for level shifting between 1.8V and 5V. However, ensure that the VREF pin is connected to the 1.8V supply, and the VCC pin is connected to the 5V supply.
