PCA9306DCTTE4 datasheet by Texas Instruments

PCA9306DCTTE4 Frequently Asked Questions (FAQs)

• What is the maximum frequency of operation for PCA9306DCTTE4?
  The maximum frequency of operation for PCA9306DCTTE4 is 400 kHz, as it is a I2C bus repeater and not a high-speed device.
• Can I use PCA9306DCTTE4 for I3C bus extension?
  No, PCA9306DCTTE4 is specifically designed for I2C bus extension and is not compatible with I3C bus protocol.
• How do I calculate the pull-up resistor value for PCA9306DCTTE4?
  The pull-up resistor value for PCA9306DCTTE4 depends on the bus capacitance, frequency of operation, and other system parameters. A good starting point is to use the I2C bus specification guidelines, which recommend a pull-up resistor value between 1 kΩ and 10 kΩ.
• Is PCA9306DCTTE4 compatible with 5V systems?
  Yes, PCA9306DCTTE4 is compatible with 5V systems, as it has a wide operating voltage range of 1.65V to 5.5V.
• Can I use PCA9306DCTTE4 for bidirectional level translation?
  No, PCA9306DCTTE4 is a unidirectional I2C bus repeater and not a bidirectional level translator. It can only translate signals from a low-voltage side to a high-voltage side, but not vice versa.
