IL 514-3E

Digital Isolators Overview

The IL514-3E is a general-purpose digital isolator manufactured by NVE Corp. It features three independent channels providing 2500Vrms isolation voltage. The device supports data rates up to 2Mbps and offers a common-mode transient immunity (CMTI) of 30kV/µs. It is housed in a 16-SOIC package with a width of 0.154 inches (3.90mm). This component serves as a low-cost alternative to optocouplers for DC-correct multi-channel applications.

Digital Isolators Feature Summary

• Provides galvanic isolation for multiple signal paths within a single compact package
• Delivers high common-mode transient immunity to maintain signal integrity in noisy environments
• Operates at data transmission speeds suitable for standard industrial communication protocols

Digital Isolators Applications

• High-power motor control cabinets
• Embedded communication systems
• General-purpose digital isolation circuits

Digital Isolators Procurement Notes

Verify the specific suffix '3E' to confirm the 16-SOIC package and channel configuration, as NVE offers variants with different pin counts and isolation ratings. Ensure compatibility with existing software tools and development environments if integrating into established designs. Confirm that the 2Mbps speed meets the system's timing requirements.

Digital Isolators Selection Notes

Select this component when multiple isolated channels are required in a space-constrained design. It is suitable for replacing optocouplers where lower cost and higher CMTI are priorities. Verify that the 2500Vrms isolation rating satisfies the safety standards of the target application.

Digital Isolators Part Context

This part belongs to NVE's family of DC-correct digital isolators. These devices utilize proprietary technology to provide reliable isolation without the degradation issues often associated with capacitive coupling over time.
