Digital Isolators

AEC-Q100Digital isolator2-channel1/1 direction50 Mbps3000 VRMSSOIC-8

ISO6721BQDRQ1 is an automotive-grade, dual-channel digital isolator with one channel in each direction, 50 Mbps capability, and 3000 VRMS isolation in a narrow SOIC-8 package.

Best for

  • Automotive isolated logic interfaces
  • Isolated CAN and LIN signal paths
  • EV/HEV battery and power-control systems

Avoid if

  • Two channels in the same signal direction are required
  • The application requires reinforced insulation beyond the D-package rating
  • Output behavior must remain defined without output-side power

Check before use

  • Confirm INA/OUTA and INB/OUTB direction for ISO6721B-Q1
  • Verify 3000 VRMS withstand and 450 VRMS working-voltage suitability
  • Place 0.1 µF bypass capacitors at both supply domains
