PCA9517ADP,118 datasheet by NXP Semiconductors

PCA9517ADP,118 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9517ADP,118 can support?
  The PCA9517ADP,118 can support I2C bus frequencies up to 400 kHz.
• Can PCA9517ADP,118 be used in a multi-master I2C bus configuration?
  Yes, the PCA9517ADP,118 can be used in a multi-master I2C bus configuration, but it requires additional external circuitry to ensure proper bus arbitration and collision detection.
• How do I ensure that the PCA9517ADP,118 is properly powered and reset?
  The PCA9517ADP,118 requires a stable power supply voltage between 2.3V and 5.5V, and a proper reset signal to ensure proper operation. A 0.1uF decoupling capacitor is recommended between VCC and GND pins.
• What is the maximum capacitance of the I2C bus that PCA9517ADP,118 can drive?
  The PCA9517ADP,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 PCA9517ADP,118 be used in a hot-swappable I2C bus configuration?
  Yes, the PCA9517ADP,118 can be used in a hot-swappable I2C bus configuration, but it requires additional external circuitry to ensure proper bus isolation and protection during hot-swapping.
