IL 613E

Overview

The IL 613E is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It utilizes GMR (Giant Magnetoresistive) sensing technology to provide electrical isolation without an isolated power supply. The device features three independent channels with a unidirectional signal flow configuration of two inputs on side 1 and one input on side 2. It offers a basic isolation voltage of 2500Vrms and supports data rates up to 40Mbps. The component operates within a supply voltage range of 3V to 5.5V and is housed in a 16-SOIC package.

Feature Summary

• Employs Giant Magnetoresistive (GMR) sensor technology for robust signal transmission
• Provides galvanic isolation without requiring an isolated power supply
• Features high common-mode transient immunity for noise-resistant operation
• Supports unidirectional data transfer across multiple independent channels

Applications

• General-purpose digital isolation in industrial control systems
• Signal isolation in microcontroller-based embedded designs
• Noise suppression in communication interfaces requiring high CMTI
• Isolation barriers in automotive electronic control units

Procurement Notes

Verify the specific suffix and revision level against the manufacturer's current datasheet, as component specifications may evolve. Confirm RoHS compliance status prior to integration, as older revisions may not meet current environmental directives. Ensure the selected package variant matches the intended PCB footprint and thermal requirements for the final assembly process.

Selection Notes

Select this component when high common-mode transient immunity is critical for system stability. The GMR technology offers advantages over capacitive or optical alternatives in specific electromagnetic environments. Verify that the required channel count and directionality align with the circuit design. Consider the operating temperature range and supply voltage compatibility with the target logic levels.

Part Context
