IL 612A-3

Overview

The IL 612A-3 is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features two unidirectional channels with a voltage isolation rating of 2500Vrms. The device supports data rates up to 10Mbps and offers a common-mode transient immunity (CMTI) of 15kV/µs. It utilizes Giant Magnetoresistive (GMR) technology for signal transmission. The component is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). It does not include isolated power capabilities.

Feature Summary

• Utilizes Giant Magnetoresistive (GMR) technology for signal isolation
• Provides high common-mode transient immunity
• Supports unidirectional data transmission
• Features a compact surface-mount package

Applications

• General purpose digital isolation
• Embedded communication systems
• High-power motor control cabinets

Procurement Notes

Verify the specific suffix when ordering, as variants like IL 612A-3E exist with identical core specifications but may differ in packaging or reel configuration. Confirm the manufacturer source is NVE Corp/Isolation Products to ensure authenticity. Check datasheets for pinout compatibility if substituting from other GMR isolators. Ensure the required isolation voltage and data rate meet system design constraints before procurement.

Selection Notes

Select this component for applications requiring robust isolation between low-voltage logic and high-voltage domains. The 10Mbps speed is suitable for standard serial communication protocols. Consider the 8-SOIC footprint for PCB layout constraints. Verify that the unidirectional channel type aligns with the signal flow requirements of the interface circuit being designed.

Part Context

This part belongs to the IL 612 series of digital isolators from NVE. It shares the same GMR technology base as related models like the IL 614-3 but differs in channel count and package type. The series is designed for cost-effective isolation solutions where high reliability and moderate data rates are prioritized over extreme speed or bidirectional complexity.

Replacement Considerations

The IL 612A-3E is a documented variant within the same product line. Other NVE GMR isolators may serve as functional substitutes if pinouts and electrical ratings match. Cross-reference datasheets for any differences in operating temperature ranges or package dimensions.
