PCA9515DP,118 datasheet by NXP Semiconductors

PCA9515DP,118 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9515DP,118 can support?
  The PCA9515DP,118 can support I2C bus frequencies up to 400 kHz.
• Can PCA9515DP,118 be used in a multi-master I2C bus configuration?
  Yes, PCA9515DP,118 can be used in a multi-master I2C bus configuration, but it requires additional external circuitry to prevent bus contention.
• How do I ensure that PCA9515DP,118 is properly powered and reset?
  To ensure proper operation, PCA9515DP,118 requires a stable power supply voltage (VCC) and a reset signal (RESET) that is asserted for at least 10 ms during power-up.
• What is the maximum capacitance of the I2C bus that PCA9515DP,118 can drive?
  The PCA9515DP,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 PCA9515DP,118 be used in a hot-swappable I2C bus configuration?
  Yes, PCA9515DP,118 can be used in a hot-swappable I2C bus configuration, but it requires additional external circuitry to prevent bus contention and ensure reliable operation.
