PCA9518APW,512 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9518APW,512 can support?
  The PCA9518APW,512 can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
• Can PCA9518APW,512 be used as a level shifter for I2C signals?
  Yes, the PCA9518APW,512 can be used as a level shifter for I2C signals, allowing communication between devices with different voltage levels (e.g., 1.8V to 5V).
• How do I configure the PCA9518APW,512 for bidirectional voltage translation?
  To configure the PCA9518APW,512 for bidirectional voltage translation, connect the VCC pin to the higher voltage level and the GND pin to the lower voltage level. Then, connect the SCL/SDA pins to the corresponding I2C bus signals.
• What is the maximum current that the PCA9518APW,512 can sink or source?
  The PCA9518APW,512 can sink or source up to 20 mA of current on the I2C bus lines, making it suitable for most I2C applications.
• Is the PCA9518APW,512 compatible with I3C bus protocol?
  No, the PCA9518APW,512 is designed for I2C bus protocol only and is not compatible with I3C bus protocol.
