PCA9564D,112 datasheet by NXP Semiconductors

PCA9564D,112 Frequently Asked Questions (FAQs)

• What is the recommended operating voltage range for PCA9564D,112?
  The recommended operating voltage range for PCA9564D,112 is 2.3 V to 5.5 V.
• How do I ensure reliable communication between the PCA9564D,112 and other I2C devices?
  To ensure reliable communication, ensure that the I2C bus is properly terminated, and the clock frequency is within the recommended range (100 kHz to 400 kHz). Also, use a pull-up resistor on the SDA line and a pull-down resistor on the SCL line.
• What is the maximum clock frequency supported by PCA9564D,112?
  The PCA9564D,112 supports clock frequencies up to 400 kHz.
• Can I use PCA9564D,112 as a level shifter for 5 V to 3.3 V conversion?
  Yes, the PCA9564D,112 can be used as a level shifter for 5 V to 3.3 V conversion, but ensure that the input voltage is within the recommended operating range.
• How do I handle bus contention on the I2C bus when using PCA9564D,112?
  To handle bus contention, use a bus arbiter or a multiplexer to ensure that only one device is driving the bus at a time. Also, implement a retry mechanism in your firmware to handle bus contention errors.
