TMUX1248DCKR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a symmetrical layout with the device placed at the center of the PCB, and signal traces routed away from the device in a star configuration to minimize noise and crosstalk.
  • To ensure signal integrity, use controlled impedance traces, minimize trace length and stubs, and use termination resistors as close to the device as possible. Also, use a solid ground plane and decouple the power supply with capacitors.
  • The recommended power-up sequence is to apply VCC first, followed by VCCA, and then the input signals. This ensures that the internal circuitry is properly biased before the input signals are applied.
  • To handle thermal management, use a heat sink or thermal pad on the exposed pad of the device, and ensure good airflow around the device. Also, minimize the thermal resistance of the PCB by using thermal vias and a thermal layer.
  • The recommended ESD protection is to use a TVS (Transient Voltage Suppressor) diode or a Zener diode with a voltage rating higher than the maximum voltage of the device, and to follow proper ESD handling procedures during assembly and testing.
