IL 712-1E

Overview

The IL 712-1E 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 100kV/µs common-mode transient immunity. The device operates on a 3V to 5.5V supply, features unidirectional channels, and has a maximum propagation delay of 15ns. It is available in an 8-SOIC package.

Feature Summary

• Employs GMR technology for high-speed signal transmission without optical components
• Provides robust electrical isolation between input and output sides
• Supports standard CMOS logic levels for direct interface compatibility

Applications

• General-purpose digital isolation in industrial systems
• Isolating microcontroller interfaces in noisy environments
• Protecting low-voltage control circuits from high-voltage power stages

Procurement Notes

Verify the specific suffix '1E' against the manufacturer's current datasheet to confirm the exact package type and temperature range, as suffixes define physical form factors. Confirm RoHS compliance status and check for any recent Product Change Notifications regarding packaging or material composition updates before finalizing procurement.

Selection Notes

Select this component when high-speed isolation exceeding 100Mbps is required alongside strong noise immunity. The GMR technology offers superior performance compared to capacitive isolators in high-noise environments. Ensure the system voltage matches the 3V to 5.5V operating range and that the SOIC package fits the PCB layout constraints.

Part Context

This part belongs to the IsoLoop family, which uses magnetic coupling instead of light or capacitance. The IL712 variant specifically offers two independent channels. It is designed to replace older optocouplers in applications demanding higher speed and better reliability over temperature variations.
