Isolators

digital isolatorintegrated isolated DC/DC3/1 channels100 Mbpsbasic insulationwide-body SOIC

ISOW7741BDFMR combines four digital isolation channels with a regulated isolated DC/DC converter in a 20-pin wide-body SOIC package. It is configured for three forward channels and one reverse channel.

Best for

  • Space-constrained isolated SPI and GPIO interfaces
  • Industrial control systems requiring integrated isolated power
  • 3.3 V or 5 V isolated peripheral supply applications

Avoid if

  • The application requires reinforced insulation rather than basic insulation
  • The isolated load exceeds the converter output-current capability
  • A separately regulated isolated supply is mandatory

Check before use

  • Confirm 3.3 V or 5 V VISOOUT configuration through VSEL
  • Budget external load and secondary isolator supply current together
  • Verify creepage, clearance, and system safety standard requirements
  • Follow the recommended VDD, VISOOUT, VISOIN, GND2, and GISOIN filtering layout
