IL 710-1ETR7

Overview

The IL710-1ETR7 is a high-speed single-channel digital isolator from NVE, designed for robust signal transmission across isolation barriers. It supports data rates up to 110 Mbps with a propagation delay of 18 ns and rise time of 4 ns. The device operates within a voltage range of 2.7 V to 5.5 V and features an isolation voltage of 800 Vrms. It utilizes magnetic coupling technology through a ceramic/polymer composite barrier, offering high common-mode transient immunity (CMTI) of 100 kV/µs. Packaged in an 8-TSSOP or 8-MSOP surface-mount format, it functions reliably between -40°C and 100°C.

Feature Summary

• Utilizes symmetric magnetic coupling via a ceramic/polymer composite barrier for long-term reliability
• Provides high common-mode transient immunity of 100 kV/µs for noise-resistant operation
• Supports serial communication protocols including RS422, RS485, and USB interfaces

Applications

• RS422 and RS485 serial communication bus isolation
• USB interface signal isolation
• General-purpose digital signal isolation in industrial systems

Procurement Notes

Verify the specific suffix 'ETR7' confirms the tape-and-reel packaging variant when ordering. Ensure the selected component matches the required 8-pin TSSOP/MSOP footprint. Confirm that the 800 Vrms isolation rating meets the safety requirements of the target application environment. Cross-reference the manufacturer part number to avoid confusion with other channel counts or package styles in the IL series.

Selection Notes

Select this component when a single isolated channel is sufficient for the design. Consider the 110 Mbps speed limit for high-frequency applications. Evaluate the 800 Vrms isolation level against system voltage requirements. The wide operating temperature range suits harsh environments. Verify compatibility with input/output voltage levels ranging from 2.7 V to 5.5 V.

Part Context

This device belongs to the IL series of digital isolators by NVE, which employ proprietary magnetic sensor technology. Unlike optical isolators, these devices do not suffer from LED degradation, ensuring virtually unlimited barrier life. The series is engineered for high-speed data transfer while maintaining electrical safety standards through non-contact signal transmission.

Replacement Considerations

Check for direct substitutes within the IL series that offer identical pinouts and electrical characteristics. Verify that any replacement maintains the 110 Mbps data rate and 100 kV/µs CMTI specifications. Ensure the alternative component supports the same 8-pin surface-mount package configuration.
