TMUX1574: About the using of TMUX1574

Part Number: TMUX1574

Hi team,

Please help me review the schematic of TMUX1574

Is it possible to select only SXA-DX for TMUX1574DYYR, and pull down the SEL pin 10k to ground?

Best regards,

Andy Liu

  • Hi Andy,

    Yes, you can pull down SEL to select only the SxA-Dx connection. If a strong pulldown is not needed, the TMUX1574 has an internal 6Mohm pulldown that can save on components.

    If this is a high frequency application, grounding the SxB pins is suggested since they can pick up noise when floating.
