PCA9510AD datasheet by NXP Semiconductors

PCA9510AD Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9510AD can support?
  The PCA9510AD can support I2C bus frequencies up to 1 MHz, but it's recommended to operate at 400 kHz or lower for reliable operation.
• Can PCA9510AD be used as a level shifter for other communication protocols besides I2C?
  No, PCA9510AD is specifically designed for I2C bus level shifting and is not recommended for use with other communication protocols.
• How do I ensure that the PCA9510AD is properly powered and biased?
  Make sure to connect VCC to a stable 3.3V or 5V power supply, and connect GND to a solid ground plane. Also, ensure that the input voltage (VCC) is within the recommended operating range (2.7V to 5.5V) and that the output voltage (VOUT) is within the recommended operating range (1.65V to 5.5V).
• What is the maximum capacitance that can be driven by the PCA9510AD?
  The PCA9510AD can drive capacitive loads up to 400 pF, but it's recommended to keep the load capacitance as low as possible to ensure reliable operation.
• Can PCA9510AD be used in a hot-swappable application?
  Yes, PCA9510AD is designed to support hot-swapping, but it's essential to ensure that the power supply to the device is stable and that the I2C bus is properly terminated to prevent bus contention.
