IL 261-1ETR7

Overview

The IL261-1ETR7 is a general-purpose digital isolator manufactured by NVE Corp. It features five independent channels capable of transmitting data at speeds up to 110 Mbps. The device provides an isolation voltage rating of 2500 Vrms and supports a common-mode transient immunity (CMTI) of 30 kV/µs. It is housed in a 16-SSOP package with a width of 3.90 mm. This component is designed for applications requiring high-speed signal transmission across isolated boundaries while maintaining electrical safety standards.

Feature Summary

• Provides five-channel digital isolation for simultaneous signal transmission
• Supports high-speed data rates up to 110 Mbps per channel
• Delivers robust common-mode transient immunity of 30 kV/µs
• Utilizes magnetic isolation technology for reliable barrier performance

Applications

• Industrial automation control systems
• Motor drive inverters and converters
• Medical equipment requiring galvanic isolation
• Power supply feedback loops

Procurement Notes

Verify the specific ordering suffix to ensure the correct package type and tape/reel configuration match your assembly requirements. Confirm that the isolation voltage ratings align with your system's safety standards. Check the operating temperature range to ensure compatibility with your environmental conditions. Validate pinout configurations against your PCB layout design before procurement.

Selection Notes

Select this component when multiple isolated channels are required within a single package footprint. Consider the 110 Mbps speed limit for signal integrity in high-frequency applications. Evaluate the 2500 Vrms isolation rating against your system's creepage and clearance requirements. Ensure the 16-SSOP package dimensions fit within your available board space constraints.

Part Context

This part belongs to the IL26x series of high-speed digital isolators from NVE. The series utilizes proprietary magnetic isolation technology, offering advantages over traditional optical or capacitive isolators. The IL261 variant specifically provides five channels, making it suitable for complex multi-signal isolation tasks in compact designs compared to single-channel alternatives.

Replacement Considerations

Direct substitutes may include other five-channel digital isolators from different manufacturers if pin-to-pin compatibility is verified. Ensure replacement parts meet or exceed the 110 Mbps speed and 30 kV/µs CMTI specifications. Verify that the replacement package matches the 16-SSOP form factor for mechanical integration.
