4.1.1 Drive Indicator LEDs

GUID-93396CD9-963A-439C-9221-F971EBAA3723-low.gifFigure 4-1 Using Logic as Indicator LED Driver Application Examples
  • Add system indicators without controller interaction required.
  • Most logic gates can drive low-current indicator LEDs (1 to 25 mA).
  • Logic functions add configurability.
  • Disable indicator LEDs as desired.
  • Find the right logic solutions through the online parametric search tool.
