    Hi Pil,

    No this wouldn't be possible. The supply would need to match your input. 30-50V. The closest fit we would have for supporting something like this would be the TMUX4827 but that would only go to 12V with a 5V supply. Unfortunately we won't have a 5V supply device that can support above the rails up to 50V.
    Do you not have a higher supply rail to feed to the VDD of the mux?

    Thanks,
    Rami
