TCA9548APWR Frequently Asked Questions (FAQs)

• What is the maximum frequency of the I2C bus that the TCA9548APWR can support?
  The TCA9548APWR can support I2C bus frequencies up to 400 kHz.
• Can the TCA9548APWR be used to control multiple I2C buses with different voltage levels?
  Yes, the TCA9548APWR has four downstream I2C ports that can operate at different voltage levels, allowing it to control multiple I2C buses with different voltage requirements.
• How does the TCA9548APWR handle bus contention and arbitration?
  The TCA9548APWR has built-in bus contention and arbitration logic that allows it to manage multiple masters on the I2C bus, ensuring that only one master can transmit at a time.
• What is the maximum number of devices that can be connected to each downstream I2C port?
  The maximum number of devices that can be connected to each downstream I2C port is limited by the I2C bus specification, which is typically around 100 devices per bus.
• Can the TCA9548APWR be used in applications that require hot-swapping of I2C devices?
  Yes, the TCA9548APWR has built-in support for hot-swapping of I2C devices, allowing devices to be added or removed from the bus without disrupting the operation of the system.
