  • Enable communication when devices have mismatched logic voltage levels
  • Prevent damage to devices that cannot support higher voltage inputs
  • Improve data rates over discrete translation solutions
  • Provide protection from disconnected peripherals
  • See online parametric search tool to find the right voltage level translator
