TMUX6208: switch of UART signal

Part Number: TMUX6208
Other Parts Discussed in Thread: TMUX6219, TMUX7219

Hi team,

My customer is looking for Mux/switch solution as switch of UART signal. Do we have some suggestions here? Whether we can only need to care about the bandwidth? Thanks.

  • Hi Frank,

    Thank you for reaching out and definitely we can support. Could you please give me some details on the use case and how you chose the TMUX6208.

    - What is the required signal voltage?

    - What are the available supply voltage rails?

    - How many channels, signal coming IN and going OUT ? (Do you have a rough schematic or block diagram)

    - Are you looking for 8:1 MUX?

    Most commonly we have seen 2ch, 1:1 (SPST) or 2ch, 2:1 (SPDT) configurations used but it can vary based on system requirement.

    All our devices can support the required UART data rate hence I am more interested in above factors.

    Thank you,



  • HI Frank,

    Just wanted to follow up on this post to see how I can help further. Below are some of the options that can be used for UART.

    2ch, 2:1 (SPDT) TMUX6219 - +/-4.5V to +/-18V or 4.5V to 36V

    2ch, 2:1 (SPDT) TMUX7219 - +/-4.5V to +/-22V or 4.5V to 44V

    2ch, 2:1 (SPDT) TS5A23157- 1.65V to 5.5V

    Thank you,
