Hi Henry

The TMUXHS4212 is fine for this application because it can support 1.8V and 3.3V supply operation and can support the minimum SD 7.0 Specification of 800mv(0.8V) Vpp voltage swing on its analog io pins.

Please let me know if you have any additional questions here and I can look into this more

Regards,

Kameron
