Isolators

digital isolatorcapacitive isolatordual channelbidirectional50 MbpsVSONfunctional isolation

ISO6521REUR is a compact dual-channel functional digital isolator for bidirectional CMOS or LVCMOS signaling, with 50 Mbps operation and default-high outputs.

Best for

  • Bidirectional isolated GPIO or control signals
  • Power-supply control interfaces
  • Industrial control and motor-drive signaling

Avoid if

  • The design requires certified safety isolation
  • More than two isolated data channels are needed
  • A default-low fail-safe output is required

Check before use

  • Confirm VCC1 and VCC2 operate only within 1.71 V to 1.89 V or 2.25 V to 5.5 V.
  • Review output state during UVLO, power loss, and floating-input conditions.
  • Keep bypass capacitors close to both VCC pins and preserve isolation spacing on the PCB.
