PCA9517AD,118 datasheet by NXP Semiconductors

PCA9517AD,118 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9517AD,118 can support?
  The PCA9517AD,118 can support I2C bus frequencies up to 400 kHz.
• Can PCA9517AD,118 be used in a multi-master I2C bus configuration?
  Yes, the PCA9517AD,118 can be used in a multi-master I2C bus configuration, but it requires external circuitry to prevent bus contention.
• How do I ensure that the PCA9517AD,118 is properly powered?
  The PCA9517AD,118 requires a 2.3V to 5.5V power supply, and it's recommended to use a decoupling capacitor of at least 100nF between VCC and GND to ensure stable operation.
• What is the maximum capacitance of the I2C bus that PCA9517AD,118 can drive?
  The PCA9517AD,118 can drive I2C bus capacitances up to 400 pF, but it's recommended to keep the bus capacitance as low as possible to ensure reliable operation.
• Can PCA9517AD,118 be used in a hot-swappable I2C bus configuration?
  Yes, the PCA9517AD,118 can be used in a hot-swappable I2C bus configuration, but it requires external circuitry to prevent bus contention and ensure reliable operation.
