IL 715-3E

Overview

The IL715-3E is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It provides galvanic isolation between circuits operating at different voltage levels using patented IsoLoop spintronic technology. The device features four transmit channels with a maximum data rate of 110 Mbps and an isolation voltage of 2.5 kVrms. It operates within a temperature range of -40°C to 125°C and supports a maximum forward voltage of 7V. Key electrical parameters include a propagation delay of 18ns, rise time of 4ns, and maximum input current of 20μA. The component is available in a 16-pin SOIC package (0.154 inch width) and complies with UL and IEC standards.

Feature Summary

• Utilizes patented IsoLoop spintronic technology for reliable data transmission
• Provides unidirectional signal isolation across four independent channels
• Designed for high common-mode transient immunity in noisy environments

Applications

• Industrial automation systems requiring circuit isolation
• Power electronics interfaces for noise reduction
• General-purpose digital isolation between disparate voltage domains

Procurement Notes

Verify the specific package variant against official documentation, as sources indicate both 16-SOIC and 8-Pin SOIC configurations for this part number. Confirm that the ordering suffix corresponds strictly to the package style without implying functional changes. Ensure compatibility with system voltage requirements before integration.

Selection Notes

Select this component when four-channel unidirectional isolation is required. The 110 Mbps data rate suits moderate-speed applications. Consider the 2.5 kVrms isolation rating for safety compliance. Verify thermal performance within the specified -40°C to 125°C range for the intended environment.

Part Context

The IL715-3E belongs to the IL series of digital isolators from NVE. These devices are designed to replace traditional optocouplers, offering improved reliability and performance. The series utilizes spintronic technology to provide robust isolation in compact packages suitable for modern electronic designs.

Replacement Considerations

IL711-2E: Offers two channels instead of four; verify channel count sufficiency.
