IL 712-3E

Overview

The IL712-3E is a two-channel digital isolator from NVE utilizing Giant Magnetoresistance (GMR) technology. It supports data rates up to 110 Mbps with a typical pulse width distortion of 2 ns. The device operates on a single supply voltage ranging from 3V to 5.5V and provides an isolation voltage of 2500 Vrms. It features low input current consumption and is available in an 8-pin SOIC surface-mount package. The component is rated for operation within a temperature range of -40°C to 100°C.

Feature Summary

• Utilizes GMR technology for high-speed signal transmission without optical components
• Provides robust galvanic isolation between circuit domains
• Compatible with standard CMOS logic levels

Applications

• General-purpose digital isolation in industrial systems
• Isolation for microcontroller communication interfaces
• Signal conditioning in noisy electrical environments

Procurement Notes

Verify the specific suffix '3E' against official NVE documentation to confirm pinout and electrical characteristics, as suffixes often denote package type or temperature grade. Ensure the source document explicitly lists IL712-3E as the active part number. Cross-reference the manufacturer's datasheet for any recent product change notices affecting this specific variant.

Selection Notes

Select the IL712-3E when a two-channel isolator with 110 Mbps speed is required in a compact SOIC package. It is suitable for applications needing 2500 Vrms isolation with low power consumption. Consider the 3V to 5.5V operating range for compatibility with various logic families. Verify that the 100°C maximum junction temperature meets the thermal requirements of the target enclosure.

Part Context

This component belongs to the IsoLoop family of digital isolators from NVE. Unlike optocouplers, it uses magnetic sensing elements to transmit signals. The IL712 variant specifically offers dual channels in a small footprint, designed to replace traditional optocouplers in space-constrained designs requiring high reliability and faster switching speeds.

Replacement Considerations

Check NVE's official substitution guide for direct replacements. Generic optocouplers may not match the 110 Mbps speed or low input current. Verify if alternative NVE models like the IL712T-2E offer the same functionality in a different package style.
