Isolators

digital isolatorfunctional isolationdual channelbidirectional50 Mbpsdefault lowVSON

ISO6521FREUR is a 50 Mbps dual-channel functional digital isolator with one channel in each direction and a low default output state.

Best for

  • Bidirectional isolated CMOS or LVCMOS control signals
  • Power converters and motor-drive control links
  • Industrial automation interfaces

Avoid if

  • Safety-isolation certification is required
  • More than 50 Mbps signaling is required
  • A fixed two-channel same-direction isolator is needed

Check before use

  • Verify the 1 forward / 1 reverse channel assignment
  • Confirm low default output behavior is suitable for the fault state
  • Provide 0.1 µF local bypass capacitors at VCC1 and VCC2
