IL 711T-1E

Overview

The IL 711T-1E is a general-purpose digital isolator from the IsoLoop series, manufactured by NVE Corp/Isolation Products. It features two channels with unidirectional signal transmission and utilizes Giant Magnetoresistive (GMR) technology for galvanic isolation. The device provides an isolation voltage of 1000Vrms and supports data rates up to 110Mbps. Key electrical parameters include a common-mode transient immunity of 100kV/µs, maximum propagation delays of 15ns, and typical rise/fall times of 1ns. It operates on a supply voltage range of 3V to 5.5V and is housed in an 8-TSSOP or 8-MSOP surface-mount package.

Feature Summary

• Utilizes GMR technology for high-speed digital isolation without requiring isolated power supplies
• Provides robust common-mode transient immunity for reliable operation in noisy environments
• Supports CMOS logic levels with low pulse width distortion for precise timing applications

Applications

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

Procurement Notes

Verify the specific suffix 'T-1E' to confirm the 1000Vrms isolation rating and TSSOP/MSOP package type, as other variants like '2E' offer higher isolation voltages. Ensure compatibility with the required operating temperature range and supply voltage specifications before finalizing procurement orders.

Selection Notes

Select this component when a compact surface-mount solution is required for moderate isolation voltage applications. It is suitable for designs needing high speed and low skew but do not require the higher 2500Vrms isolation provided by PDIP or SOIC variants. Consider the 8-pin footprint constraints during PCB layout planning.

Part Context

This part belongs to the IsoLoop family, which distinguishes itself by using magnetic coupling rather than capacitive or optical methods. The IL711 series offers true logic integration, combining isolation barriers with signal conditioning in a single package, eliminating the need for external components typically required in discrete isolation solutions.

Replacement Considerations

The IL 711T-2E serves as a direct pin-compatible alternative offering increased isolation voltage of 2500Vrms while maintaining similar electrical characteristics and package dimensions.
