Digital Isolators

AEC-Q100digital isolatorfour channeldefault low100 Mbps5000 VRMSwide-body SOIC

ISO7740FQDWRQ1 is a four-channel, automotive-qualified reinforced digital isolator for unidirectional CMOS or LVCMOS signal isolation. Its F suffix provides default-low outputs during input-side power or signal loss.

Best for

  • Automotive control systems requiring four signals across an isolation barrier
  • Motor-control and power-conversion control signals
  • CMOS or LVCMOS level translation across isolated domains

Avoid if

  • A bidirectional or differential bus transceiver is required
  • The required isolation rating exceeds the DW package ratings
  • A default-high output state is required during input loss

Check before use

  • Verify 5000 VRMS UL 1577 isolation and application-specific working-voltage requirements
  • Verify EN2 is high or open when side-2 outputs must be active
  • Keep VCC1/GND1 and VCC2/GND2 grounds isolated as required by the system
