GUID-F1A058B9-93C7-4CFB-93BE-E83C0063985F-low.gifFigure 2-11 Using Voltage Translation with an SD Card Communication Bus
  • 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
  • Protect controller while SD Card is not connected
  • Find the right voltage level translator through the online parametric search tool
