• Features low power consumption suitable for battery-operated devices

Applications

• Isolated data transmission
• Fieldbus isolation
• High speed digital systems

Procurement Notes

Verify the specific suffix '3B' against the manufacturer's latest documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or revision. Ensure the component meets required safety certifications such as UL 1577 or IEC 61010-1 for your specific application environment. Cross-reference the datasheet for any updates on operating temperatures or isolation ratings.

Selection Notes

Select this component when high-speed signal isolation is required between circuits with different ground potentials. The SOIC package is suitable for surface mount applications. Consider the 2.5 kVrms isolation rating for noise immunity in industrial environments. Verify that the input voltage levels match the system's logic family requirements.

Part Context

The IL711 series represents NVE's early digital isolators utilizing proprietary technology. The IL711-3B specifically denotes the SOIC package variant within this family. These components were designed to replace transformer-based isolators in compact designs. The series is known for its low power consumption and high reliability in harsh electromagnetic environments.

Replacement Considerations

IL711-3E is a documented equivalent offering similar specifications in the same SOIC package. Check for updated revisions or newer generations from NVE if long-term availability is a concern.
