IL 712-1ETR7

Overview

The IL 712-1ETR7 is a dual-channel digital isolator from the IsoLoop series, utilizing Giant Magnetoresistive (GMR) technology. It provides 2500Vrms isolation with a typical data rate of 110Mbps and a common-mode transient immunity of 100kV/µs. The device operates on a single supply voltage between 3V and 5.5V, featuring unidirectional channels in an 8-TSSOP or 8-MSOP package. It supports CMOS logic levels for +5V and +3.3V systems.

Feature Summary

• Employs GMR technology for high-speed signal transmission without optical components
• Provides robust common-mode transient immunity to minimize noise-induced errors
• Supports standard CMOS logic compatibility for easy integration

Applications

• RS422 and RS485 communication interfaces
• General-purpose digital isolation in industrial control systems
• Isolating microcontroller units from peripheral devices

Procurement Notes

Verify the specific suffix 'ETR7' confirms the tape-and-reel packaging format required for automated assembly processes. Confirm that the manufacturer designation matches NVE Corp/Isolation Products to ensure component authenticity and traceability. Check for RoHS compliance status if environmental regulations apply to the final product design.

Selection Notes

Select this component when high-speed bidirectional isolation is not required, as it features unidirectional channels. It is suitable for applications demanding fast response times and high noise immunity in compact surface-mount footprints. Ensure the operating temperature range meets the system's thermal requirements.

Part Context

This part belongs to the IsoLoop family, which distinguishes itself by using magnetic sensing rather than capacitive or optical methods. This architecture typically offers superior reliability and performance in harsh electromagnetic environments compared to traditional isolation technologies.

Replacement Considerations

The IL 712-2E is listed as a substitute option. Verify channel configuration and pinout compatibility before substitution.
