    Hi Keiven,

    For TMU6121, the recommneded operating conditions for dual supply is Vss range to be within -16.5~ -5V, and Vdd to be within 5~16.5V.

    So Vdd=20V in dual supply scenario would exceed the recommended operating conditions. Please see below for the TMUX6121 datasheet recommended operating conditions.

    What is your customer's application scenario?

    Thank you,

    Helen
