IL 611-1ETR7

Overview

The IL611-1ETR7 is a general-purpose digital isolator from NVE Corp/Isolation Products. It features two channels with a maximum data rate of 40 Mbps and an isolation voltage of 2500 Vrms. The device operates on a supply voltage between 3V and 5.5V, with a typical propagation delay of 8 ns and rise/fall times of 2 ns. It offers a common-mode transient immunity (CMTI) of 15 kV/µs. The component is housed in an 8-TSSOP or 8-MSOP package and supports communication protocols including CAN, I2C, RS232, RS422, RS485, and SPI.

Feature Summary

• Galvanic signal transmission across a barrier for circuit separation
• High common-mode transient immunity of 15 kV/µs
• Supports multiple digital communication protocols

Applications

• CAN bus isolation
• I2C interface isolation
• RS485 communication isolation

Procurement Notes

Verify the specific suffix 'ETR7' to confirm tape-and-reel packaging and pin configuration. Ensure the selected variant matches the required channel count and isolation voltage ratings for your design. Cross-reference the manufacturer's latest datasheet to confirm RoHS compliance status and operating temperature range specifications before finalizing procurement.

Selection Notes

Select this component when a compact 8-pin solution is required for isolating low-speed digital signals. It is suitable for applications needing moderate data rates up to 40 Mbps. Consider the package dimensions and thermal characteristics relative to your PCB layout constraints. Verify that the input/output logic levels are compatible with the connected microcontrollers or transceivers.

Part Context

This part belongs to the IL611 series of digital isolators by NVE. These devices utilize proprietary magnetic sensor technology to provide galvanic isolation without optical components. The series is designed for robust performance in noisy environments, offering high reliability and long-term stability compared to traditional optocoupler alternatives.

Replacement Considerations

Check for direct equivalents within the IL611 family, such as the IL611-1E for tube packaging. Evaluate other NVE isolators like the IL614 for additional channel requirements. Ensure any substitute maintains the same 2500 Vrms isolation rating and 40 Mbps data speed.
