IL 515E

Overview

The IL515E is a four-channel digital isolator from the NVE IL series, designed for parallel bus isolation. It operates at a maximum data rate of 2 Mbps with a common-mode transient immunity (CMTI) of 30 kV/µs. The device features a 2500 Vrms isolation voltage and supports a supply voltage up to 5.5V. It is housed in a 16-pin SOIC package with a width of 7.50mm.

Feature Summary

• Provides galvanic isolation for four independent digital channels
• Utilizes spintronic technology as an alternative to optocouplers
• Includes an internal clock for DC-correct signal transmission

Applications

• Parallel bus isolation
• General-purpose digital isolation
• Industrial control systems requiring low-cost isolation

Procurement Notes

Verify the specific suffix against official datasheets to confirm pinout and electrical characteristics. Ensure the supplier provides documentation confirming the component is the genuine IL515E variant. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit or obsolete stock.

Selection Notes

Select this component when a low-cost alternative to optocouplers is required for parallel buses. It is suitable for applications needing moderate speed up to 2 Mbps rather than high-speed interfaces. Consider the 16-SOIC package constraints and verify that the 30 kV/µs CMTI meets the noise environment requirements.

Part Context

The IL515E belongs to the NVE IL family of spintronic isolators. Unlike higher-speed variants such as the IL715, this model prioritizes cost-effectiveness and DC correction over raw data throughput. It leverages Giant Magnetoresistive (GMR) sensor technology for reliable signal transfer across the isolation barrier.

Replacement Considerations

The IL715 offers higher speed but may not be a direct drop-in replacement if cost is a primary constraint. Verify pin compatibility and thermal performance before substituting with other general-purpose digital isolators.
