IL 614-3

Overview

The IL 614-3 is a general-purpose digital isolator manufactured by NVE Corp. It features three independent channels with a rated isolation voltage of 2500Vrms. The device supports data rates up to 40Mbps and provides common-mode transient immunity (CMTI) of 15kV/µs. It is housed in a 16-SOIC package with a width of 3.90mm.

Feature Summary

• Provides galvanic isolation for digital signal transmission
• Offers high common-mode transient immunity for noise rejection
• Supports general-purpose embedded communication applications

Applications

• High-power motor control cabinets
• Embedded communication systems
• HMI and display projects with external peripherals

Procurement Notes

Verify the specific suffix '-3' against official NVE documentation to confirm channel count and pinout configuration. Ensure the required isolation voltage rating meets system safety standards. Confirm package dimensions match the PCB footprint requirements before procurement.

Selection Notes

Select this component when three isolated channels are required for general-purpose digital signals. Consider the 40Mbps data rate limit for signal integrity. Evaluate the 15kV/µs CMTI specification against the noise environment of the target application to ensure reliable operation.

Part Context

This part belongs to NVE's digital isolator portfolio, utilizing magnetic isolation technology. It serves as an alternative to optical or capacitive isolators in industrial and automotive environments where reliability and longevity are critical.

Replacement Considerations

Check for direct substitutes within the IL series, such as the IL 614E, noting differences in data rate and package width. Verify pin compatibility and electrical specifications before substitution.
