IL 711-2B

Overview

The IL711-2B is a dual-channel digital isolator from the NVE IsoLoop family, utilizing Giant Magnetoresistive (GMR) technology for galvanic isolation. It supports data rates up to 110 Mbps with a maximum propagation delay of 18 ns and typical rise/fall times of 4 ns. The device operates on a supply voltage range of 3V to 5.5V and provides an isolation voltage of 2500 Vrms. It features a low input current of 15 μA and maintains functionality across an operating temperature range of -40°C to 125°C. The component is housed in an 8-pin PDIP package.

Feature Summary

• Utilizes GMR sensor technology for high-speed signal transmission without optical components
• Provides robust galvanic isolation between input and output circuits
• Compatible with standard +5V and +3.3V CMOS logic levels

Applications

• Isolated data transmission systems
• Fieldbus isolation interfaces
• High-speed digital system interconnects

Procurement Notes

Verify the specific suffix 'B' against official manufacturer documentation to confirm pinout and electrical characteristics, as suffixes often denote package variations or specific manufacturing revisions. Ensure the selected variant matches the required thermal and voltage specifications for the target application environment.

Selection Notes

Select this component when high-speed isolation is required alongside low power consumption. The GMR technology offers superior immunity to magnetic interference compared to capacitive isolators. Verify that the 8-pin DIP package fits the available PCB real estate and that the 2500 Vrms isolation rating meets the safety requirements of the circuit design.

Part Context

The IL711 series belongs to NVE's IsoLoop family, which integrates magnetoresistive sensors and CMOS drivers on a single chip. This architecture eliminates the need for external magnetic coupling elements, resulting in a compact solution for general-purpose digital isolation applications requiring high reliability and speed.

Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify compatibility regarding channel count, isolation voltage, and package dimensions before substitution.
