7.3.3 Powered-off Protection

When the TMUXHS221F is powered off the I/Os of the device remain in a high-Z state. The crosstalk, off-isolation, and leakage remain within the Electrical Specifications.

This prevents errant voltages from reaching the rest of the system and maintains isolation when the system is powering up.
