TCA9548APWR Frequently Asked Questions (FAQs)

  • The TCA9548APWR can support I2C bus frequencies up to 400 kHz.
  • 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.
  • 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.
  • 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.
  • 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.
