IL 712T-1E

Overview

The IL 712T-1E is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It utilizes Giant Magnetoresistive (GMR) technology to provide electrical isolation without an integrated isolated power supply. The device features two independent channels with unidirectional signal transmission. It supports data rates up to 40Mbps and offers a basic isolation voltage of 1000Vrms. The component operates within a supply voltage range of 3V to 5.5V and is available in an 8-TSSOP or 8-MSOP surface-mount package.

Feature Summary

• Utilizes GMR sensing technology for robust signal isolation
• Provides bidirectional channel independence with unidirectional transmission
• Operates without an internal isolated power supply

Applications

• General-purpose digital isolation in industrial control systems
• Signal isolation in motor drive circuits
• Data communication interfaces requiring galvanic separation

Procurement Notes

Verify the specific suffix 'T-1E' against official NVE documentation to confirm the exact package variant and tape-and-reel configuration. Ensure compatibility with the target PCB footprint for the 8-TSSOP or 8-MSOP form factor. Cross-reference the manufacturing date code and RoHS compliance status with current distributor listings to guarantee adherence to environmental regulations.

Selection Notes

Select this component when a compact surface-mount solution is required for low-to-moderate speed digital isolation. The GMR technology offers high common-mode transient immunity compared to capacitive alternatives. Consider the 1000Vrms isolation rating as sufficient for lower voltage primary-side applications. Evaluate the 40Mbps data rate limit against system timing requirements before finalizing the design.

Part Context

This part belongs to the IsoLoop family of magnetic digital isolators. Unlike optocouplers, it does not suffer from LED degradation over time. The IL 712 variant specifically denotes a dual-channel configuration. The 'T' suffix typically indicates a tape-and-reel packaging option suitable for automated assembly processes.

Replacement Considerations

IL 712T-2E: Offers higher 2500Vrms isolation rating while maintaining similar pinout and functionality.
