Digital Isolators

ISO6721RBDR is a 50 Mbps, dual-channel digital isolator for isolated CMOS or LVCMOS signals. Its channel arrangement provides one signal path in each direction and uses default-high outputs during input-side power loss.

Best for

  • Bidirectional isolated CMOS control signals
  • Industrial control interfaces
  • Power-supply and motor-drive control

Avoid if

  • Applications requiring reinforced isolation without separate safety evaluation
  • Interfaces needing a dedicated protocol transceiver rather than isolated single-ended logic

Check before use

  • Confirm ISO6721RB pinout against the PCB footprint
  • Confirm default-high behavior is safe for loss-of-input-power conditions
  • Place 0.1 µF bypass capacitors close to VCC1/GND1 and VCC2/GND2
