IL 612A-2E

Overview

The IL 612A-2E is a general-purpose digital isolator manufactured by NVE. It features two independent channels with unidirectional signal transmission capability. The device utilizes Giant Magnetoresistive (GMR) technology for galvanic isolation, providing an isolation voltage of 2500Vrms. It supports data rates up to 10Mbps and offers a common-mode transient immunity (CMTI) of 15kV/µs. The component operates within a supply voltage range of 3V to 5.5V and functions reliably across an operating temperature range of -40°C to 85°C.

Feature Summary

• Utilizes GMR technology for reliable galvanic isolation
• Provides high common-mode transient immunity
• Supports unidirectional signal transmission

Applications

• General purpose digital isolation
• Signal transmission in noisy environments
• Industrial control systems

Procurement Notes

Verify the specific package type upon ordering, as listings may indicate either 8-DIP or 8-SOIC configurations for this part number. Confirm RoHS compliance status directly with the supplier. Ensure the selected variant matches the required pinout and mounting style for your PCB design. Cross-reference the manufacturer's latest datasheet to confirm current production status and any potential obsolescence notices before finalizing procurement.

Selection Notes

Select this component when a robust, low-power digital isolator is required for applications demanding high CMTI. The GMR technology offers advantages over capacitive or optical alternatives in certain harsh environments. Consider the 2500Vrms isolation rating for safety requirements. Evaluate the 10Mbps speed limit against system timing constraints. Verify that the unidirectional channel configuration aligns with the signal flow requirements of the target circuit design.

Part Context

This device belongs to the NVE IL6xx series of digital isolators. These components are designed to replace traditional optocouplers in many applications. The series leverages proprietary GMR sensor technology. This approach provides improved performance metrics compared to legacy isolation technologies. The IL 612A-2E represents a specific configuration within this broader product family.

Replacement Considerations

The IL 612A-3E is a documented alternative within the same product line. Both devices share similar core specifications and GMR technology. Verify pin compatibility and package dimensions before substitution. Check if the specific suffix indicates differences in packaging or testing criteria.
