Isolators

digital isolatorfunctional isolationCMOSSOIC-850 Mbps

ISO6521FDR is an 8-pin SOIC dual-channel functional digital isolator with one forward and one reverse channel, 50 Mbps operation, and low default outputs.

Best for

  • Single-ended CMOS or TTL signal isolation
  • Logic-level translation
  • Power-supply and industrial control signal paths

Avoid if

  • Certified safety isolation is required without additional qualification
  • The application exceeds the specified supply, voltage, current, or data-rate limits

Check before use

  • VCC1 and VCC2 operating ranges
  • Low default output behavior
  • Output loading and unpowered-side conditions
  • PCB isolation distances
