TMUX1109: Input protection, clamp to VDD/VSS ?

Part Number: TMUX1109
Other Parts Discussed in Thread: TVS2701

We want to use TMUX1109 in a project and the TMUX has VS, VD max of VDD+0.5V. Is there any internal clamp-diodes on the input of the TMUX1109?

We have 6.8kohm in series with the input and BAV199 external clamp diodes to VDD/VSS. The Vf of the BAV199 is up to 0.7V so this might go over TMUX1109 spec of VDD+0.5V. Is this ok?

See schematic below.
