Should I use voltage level translate with 12V/24V supply of WS2812?

Some WS2812 use 12V/24V supply, should I use voltage level translator between WS2812's DIN pin and Arduino's Pin?

WS2812 document seems not descript for DIN pin internal equivalent circuit.

The "real" WS2812 runs on 5V but there are variations. In every case the data signal (from the Arudino) is 5V.
