IL 712T-3

Overview

The IL 712T-3 is a general-purpose digital isolator from the IsoLoop series by NVE Corp/Isolation Products. It features two channels with unidirectional signal transmission and utilizes Giant Magnetoresistive (GMR) technology. The device provides 2500Vrms isolation voltage and supports data rates up to 110Mbps. It operates within a supply voltage range of 3V to 5.5V and functions across an extended temperature range of -40°C to 125°C. The component is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). Key performance metrics include a common-mode transient immunity of 100kV/µs, maximum propagation delays of 15ns for both low-to-high and high-to-low transitions, and a typical rise/fall time of 1ns.

Feature Summary

• Utilizes GMR sensor technology for magnetic coupling without capacitive or optical elements
• Provides robust common-mode transient immunity against electrical noise
• Supports high-speed data transmission with low propagation delay
• Operates on standard single-supply voltages without requiring isolated power

Applications

• General-purpose digital isolation in industrial control systems
• Signal isolation in mixed-signal environments
• Data communication interfaces requiring galvanic isolation

Procurement Notes

Verify the specific suffix 'T-3' confirms the 8-SOIC surface-mount package variant. Confirm RoHS compliance status and REACH registration details as required by regional regulations. Ensure the ordering part number matches the exact channel configuration and package dimensions specified in the official datasheet to avoid integration errors.

Selection Notes

Select this component when high CMTI is critical for system stability in noisy environments. The GMR technology offers superior reliability compared to capacitive isolators in certain harsh conditions. Verify that the 110Mbps data rate meets the application requirements and that the 8-SOIC footprint fits the PCB layout constraints.

Part Context

This device belongs to the IsoLoop family of digital isolators, which distinguishes itself by using magnetic coupling rather than traditional capacitive or optical methods. The IL712 variant specifically denotes a dual-channel configuration. The 'T-3' suffix indicates the tape-and-reel packaging format and the SOIC package style, differentiating it from PDIP or other package options within the same functional family.

Replacement Considerations

Cross-reference with IL 712-3E for identical specifications in different packaging. Check IL 712T-2E for similar performance in alternative configurations. Verify pinout compatibility before substituting with other manufacturers' devices such as ISO7220 variants.
