Digital Isolators

Digital isolatorIntegrated isolated DC/DCReinforced isolation5000 VRMS100 MbpsSOIC-WB-16Default low

ISOW7841FDWER integrates four reinforced digital isolation channels and an isolated DC/DC supply in a 16-pin wide-body SOIC. It is the default-low, 3-forward/1-reverse channel option.

Best for

  • Space-constrained isolated control interfaces
  • Isolated SPI-style links requiring 3 forward and 1 reverse channel
  • Applications needing a small integrated isolated supply

Avoid if

  • The isolated load requires more than the converter output-current capability
  • A different channel direction or default-high output is required
  • The application needs a standards-compliant bus transceiver rather than CMOS/LVCMOS isolation

Check before use

  • Set SEL correctly: connect to VISO for 5 V output; connect to GND2 for 3.3 V output.
  • Size VCC and VISO decoupling capacitors close to the device.
  • Derate isolated output current at elevated ambient temperature where specified.
