ISO6520FDR is a two-channel, one-way CMOS digital isolator for transferring logic signals across a functional isolation barrier. The F version defaults its outputs low when the input signal or input-side power is lost.

Best for

  • Two unidirectional PWM or control signals
  • Isolated CMOS and LVCMOS logic links
  • Power conversion and industrial control circuits

Avoid if

  • The application requires standards-agency-certified safety isolation
  • Bidirectional communication is required through the same two channels
  • A default-high output is required during input power or signal loss

Check before use

  • Verify the functional-isolation rating is acceptable for the system standard.
  • Place a 0.1 µF bypass capacitor close to each VCC pin.
  • Maintain PCB creepage and clearance across the isolation barrier.
  • Verify the default-low output state is safe for the controlled load.
