3v3 VLogic for DG212
https://datasheets.maximintegrated.com/en/ds/DG202-DG212.pdf
  
  Compared to the original manufacturer’s products, Maxim’s DG202/DG212
  consume very little power, making them better suited for portable
  applications. Maxim has also eliminated the need for the third logic
  power supply (VL) that is required for the operation of the original
  manufacturer’s DG212 without sacrificing compatibility.


I don't have any experience with the chip. I suspect that the VL voltage may bias the transistor performance, thus implies the rest of the system. I also searched from other manufacture datasheet state that the Absolute Maximum Ratings of VL to Ground is -0.3V to 25V. You may need to test it yourself for your specific application to see any effects.

But if you need an answer fast, I think you should use the Maxim version instead to avoid uncertainty.
