TMUX7219DGKR Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the TMUX7219DGKR is 1.65 V to 5.5 V.
  • To ensure signal integrity, use a low-ESR capacitor (e.g., 0.1 μF) between VCC and GND, and keep the signal traces as short as possible. Additionally, use a ground plane and avoid routing signals near the mux's switching nodes.
  • The maximum switching frequency of the TMUX7219DGKR is 100 kHz. However, it's recommended to limit the switching frequency to 10 kHz to 20 kHz for optimal performance and to minimize power consumption.
  • During power-up, ensure that the VCC pin is powered up before the control signals (Sx, EN). During power-down, ensure that the control signals are disabled before powering down the VCC pin.
  • Keep the signal traces as short as possible, and use a star topology for the signal connections. Route the signals away from the mux's switching nodes and avoid crossing signal traces over the mux's power pins.
