IL 612A-2

Overview

The IL612A-2E is a general-purpose digital isolator from NVE Corp/Isolation Products. It features two independent channels with 2500Vrms isolation voltage. The device operates on a supply voltage of 3V to 5.5V and supports data rates up to 10Mbps. It utilizes GMR technology for signal transmission, offering high common-mode transient immunity of 15kV/µs. The component is available in an 8-DIP package.

Feature Summary

• Utilizes Giant Magnetoresistance (GMR) technology for signal isolation
• Provides enhanced circuit performance compared to standard optocoupler solutions
• Features passive input design with CMOS outputs

Applications

• General purpose digital isolation
• Industrial communication interfaces
• Medical equipment signal isolation

Procurement Notes

Verify the specific suffix (e.g., -2E vs -3E) against the required package type, as the -2E typically denotes an 8-DIP package while other suffixes may indicate SOIC. Confirm that the 2-channel configuration meets the system requirements. Ensure the operating temperature range of -40°C to 85°C aligns with the application environment. Cross-reference the datasheet for pinout compatibility if replacing existing components.

Selection Notes

Select this component when a robust, low-noise digital isolator is needed for applications requiring high reliability. The GMR technology offers superior EMC performance compared to optical alternatives. Consider the 2500Vrms isolation rating for safety-critical circuits. Evaluate the 10Mbps data rate capability against the system's bandwidth needs. The passive input feature simplifies interface design by reducing external component count.

Part Context

NVE Corporation specializes in digital isolators using proprietary GMR semiconductor materials. The IL612 series represents their general-purpose isolator line, designed to replace traditional optocouplers. These devices are known for minimal internal EMC noise generation due to DC signal processing within the barrier. The product line includes various channel counts and package options to suit diverse industrial and commercial applications.

Replacement Considerations

The IL612A-3E is a confirmed substitute part number, offering identical electrical specifications but housed in an 8-SOIC package instead of the 8-DIP format. Verify footprint compatibility before substitution. No other direct substitutes are documented in the provided source material.
