TMUX6136: I can't get the CAD file of TMUX6163 from ti.com.

Part Number: TMUX6136

I need package file of TMUX6136 in an Altium Designer project. But there is no CAD file(.bxl) in ti.com. So can you help and offer me the CAD file of TMUX6136, or a pin-to-pin package file which is same as TMUX6136.

Thanks a lot.
