PCA9515AD,112 datasheet by NXP Semiconductors

PCA9515AD,112 Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that PCA9515AD,112 can support?
  The PCA9515AD,112 can support I2C bus frequencies up to 400 kHz.
• Can PCA9515AD,112 be used in a multi-master I2C bus configuration?
  Yes, the PCA9515AD,112 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 PCA9515AD,112 is properly powered and reset?
  The PCA9515AD,112 requires a stable power supply voltage between 2.3V and 5.5V, and a reset signal (RESET) that is asserted low for at least 1 ms to ensure proper operation.
• What is the maximum capacitance of the I2C bus that PCA9515AD,112 can drive?
  The PCA9515AD,112 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 PCA9515AD,112 be used in a hot-swappable I2C bus configuration?
  Yes, the PCA9515AD,112 can be used in a hot-swappable I2C bus configuration, but it requires external circuitry to prevent bus contention and ensure reliable operation.
