TCA9544APWR Frequently Asked Questions (FAQs)

  • The TCA9544APWR can support I2C bus frequencies up to 400 kHz, but it's recommended to limit the frequency to 100 kHz for reliable operation.
  • Yes, the TCA9544APWR can switch between multiple I2C buses with different voltage levels, but the voltage on each bus must be within the recommended operating range of 1.65 V to 5.5 V.
  • To ensure correct switching, make sure to use the correct address pins (A0, A1, and A2) to select the desired bus, and use the EN pin to enable or disable the switch. Also, ensure that the I2C bus is idle before switching to a new bus.
  • The TCA9544APWR can sink or source up to 10 mA of current on each I2C bus, but it's recommended to limit the current to 5 mA for reliable operation.
  • Yes, the TCA9544APWR can switch between I2C buses with different clock stretching requirements, but it's recommended to ensure that the clock stretching requirements of each bus are compatible with the device's clock stretching capabilities.
