High voltage level for bidirectional level translator

Hello,

For product no 2595, how does one calculate the 18V ? Can I run the level converter with 20V high side voltage too?

thanks

Hi.

The absolute maximum input voltage of the FET on those level shifters is 20V, but we do not recommend using them with an input over 18V, since higher voltages do not leave room for any noise or fluctuation.
