IL 516E

Overview

The IL 516E is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features four channels and operates with a data rate of 2 Mbps. The device provides an isolation voltage of 2500Vrms and exhibits a common-mode transient immunity (CMTI) of 30kV/µs. It is housed in a 16-SOIC package, measuring 0.295 inches or 7.50mm in width.

Feature Summary

• Provides galvanic isolation for digital signal transmission across electrical barriers
• Utilizes GMR technology for high-speed data transfer capabilities
• Offers robust common-mode transient immunity to maintain signal integrity

Applications

• General purpose digital isolation circuits
• Industrial communication interfaces requiring isolated channels
• Data acquisition systems needing channel separation

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and functional variations. Ensure the 16-SOIC package dimensions align with PCB layout requirements. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement specifications.

Selection Notes

Select this component when four isolated channels are required within a single package footprint. Consider the 2 Mbps data rate limit for application speed requirements. Evaluate the 30kV/µs CMTI specification against noise environments to ensure reliable operation without external filtering.

Part Context

This part belongs to the IsoLoop family of digital isolators from NVE. These devices leverage Giant Magnetoresistance sensing technology rather than optical or capacitive methods. This architecture typically offers superior reliability and longevity compared to traditional optocoupler technologies in harsh industrial environments.
