IL 612-3E

Overview

The IL 612-3E is a general-purpose digital isolator from NVE Corp/Isolation Products. It features two channels with unidirectional signal paths, utilizing Giant Magnetoresistive (GMR) technology for galvanic isolation. The device provides an isolation voltage of 2500Vrms and supports data rates up to 10Mbps. It exhibits a common-mode transient immunity (CMTI) of 15kV/µs. Packaged in an 8-SOIC format with a width of 0.154 inches (3.90mm), it operates without isolated power.

Feature Summary

• Utilizes GMR technology for high-performance signal coupling
• Provides flexible wide-range input voltage compatibility
• Features CMOS outputs for enhanced circuit integration

Applications

• Embedded communication applications
• Galvanic isolation between circuits at different voltage levels
• General-purpose digital isolation tasks

Procurement Notes

Verify the specific suffix against official NVE documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required channel directionality and package dimensions for the target PCB layout. Cross-reference datasheets to validate performance parameters before finalizing procurement decisions.

Selection Notes

Select this component when GMR-based isolation offers advantages over optical solutions. Consider its passive input nature and CMOS output structure for system integration. Evaluate the 10Mbps data rate and 15kV/µs CMTI against application requirements to ensure adequate noise immunity and speed.
