IL 715T

Overview

The IL 715T is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It features four unidirectional channels with a 2500Vrms isolation voltage and supports data rates up to 110Mbps. The device utilizes Giant Magnetoresistive (GMR) technology and operates on a single supply voltage of 3V to 5.5V. It offers a common-mode transient immunity of 100kV/µs and functions within an extended temperature range of -40°C to 125°C. The component is housed in a 16-SOIC surface-mount package.

Feature Summary

• Utilizes GMR sensor technology for high-speed signal transmission
• Provides robust electrical isolation between circuit sections
• Supports high common-mode transient immunity for noisy environments

Applications

• Industrial communication bus isolation
• Power electronics control circuits
• Medical equipment signal interfaces

Procurement Notes

Verify the specific suffix (e.g., T, TR) to confirm the exact packaging type, such as tube or tape-and-reel, as this affects handling procedures. Ensure the selected variant matches the required channel count and isolation voltage specifications for the target application. Cross-reference official datasheets to confirm RoHS compliance status and lead times directly with the manufacturer.

Selection Notes

Select this component when four isolated channels are required in a compact surface-mount footprint. The IsoLoop technology provides superior performance compared to traditional optical isolators in terms of speed and power consumption. Consider the operating temperature range and supply voltage requirements to ensure compatibility with the system design constraints.

Part Context

The IL 715T belongs to the IsoLoop family of digital isolators, which leverage magnetic sensing principles rather than optical components. This family includes variants with different channel counts and packages, such as the IL 711T-2E and IL 715T-3E. These devices are designed to replace optocouplers in applications demanding higher reliability and faster data rates.

Replacement Considerations

Direct substitutes include other NVE IsoLoop parts like the IL 715T-3E for specific packaging variations. Evaluate pin-compatible alternatives from other manufacturers only if they match the 2500Vrms isolation rating and 110Mbps data rate specifications.
