TCA9543ADR Frequently Asked Questions (FAQs)

  • The TCA9543ADR can support I2C bus frequencies up to 400 kHz.
  • Yes, the TCA9543ADR is a bi-directional translator, which means it can translate between different voltage levels, such as 1.8V, 2.5V, 3.3V, and 5V.
  • The TCA9543ADR is a 4-channel I2C bus multiplexer, which means it can multiplex up to 4 I2C buses.
  • The TCA9543ADR can sink or source up to 10mA of current on each channel.
  • No, the TCA9543ADR does not require any external components for operation, as it has internal pull-up resistors on the I2C bus lines.
