IL 260-1E

Overview

The IL260-1E is a high-speed five-channel digital isolator manufactured by NVE Corp using patented IsoLoop technology. It provides unidirectional signal isolation with a typical data rate of 110 Mbps and a common mode transient immunity of 30 kV/µs. The device features reinforced isolation ratings of up to 6 kVRMS for the VE-series variants, ensuring robust performance in noisy environments. It operates within an extended temperature range of -40°C to 85°C and is housed in a 16-SSOP package.

Feature Summary

• Utilizes patented IsoLoop technology for reliable signal transmission
• Provides high-speed data isolation with typical rates of 110 Mbps
• Offers very high reinforced isolation capabilities up to 6 kVRMS
• Features low quiescent current consumption per channel

Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power supply feedback loops
• Motor drive gate driver interfaces

Procurement Notes

Verify the specific suffix (e.g., -1E) against official NVE documentation to confirm pinout configuration and isolation rating variations. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference datasheet revision dates to confirm compatibility with current design specifications before finalizing procurement orders.

Selection Notes

Select this component when high-speed unidirectional isolation is required for multiple channels simultaneously. Consider the 110 Mbps data rate and 30 kV/µs CMTI for applications involving fast switching signals. Evaluate the 16-SSOP package constraints for PCB layout space and thermal management requirements relative to other available isolator families.

Part Context

The IL260 series belongs to NVE's family of high-speed digital isolators leveraging magnetoresistive coupling. This specific model offers five isolated channels, distinguishing it from lower-channel variants like the IL261 or IL262. It serves as a critical interface component between microcontrollers and power stages in electrically noisy industrial settings.

Replacement Considerations

Public confirmed substitutes include Silicon Labs SI8650 and Skyworks SI8650. Verify pin-to-pin compatibility and electrical parameter equivalence, particularly isolation voltage and data rate, before substituting. Check manufacturer recommendations for direct replacements to ensure system integrity.
