IL 711-1ETR7

Overview

The IL 711-1ETR7 is a digital isolator from NVE Corp utilizing IsoLoop® GMR technology. It provides galvanic isolation with a rating of 2500Vrms and supports two channels in a unidirectional configuration. The device operates within a supply voltage range of 3V to 5.5V and features a data rate of 110Mbps. Key electrical parameters include a maximum propagation delay of 15ns, typical rise and fall times of 1ns, and a common-mode transient immunity of 100kV/µs. It is housed in an 8-TSSOP or 8-MSOP package with a width of 3.00mm.

Feature Summary

• Utilizes Giant Magnetoresistive (GMR) sensing technology for high-speed signal transmission across isolation barriers.
• Provides robust common-mode transient immunity to maintain signal integrity in noisy environments.
• Offers low pulse width distortion and minimal channel-to-channel skew for precise timing applications.

Applications

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

Procurement Notes

Verify the specific suffix 'ETR7' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 8-TSSOP/8-MSOP footprint matches the target PCB design constraints. Ensure compliance with RoHS3 standards and check for any recent Product Change Notifications regarding the IsoLoop series manufacturing updates.

Selection Notes

Select this component when high-speed bidirectional isolation is not required, as the IL 711 series offers unidirectional channels only. Consider the 110Mbps data rate capability against system bandwidth requirements. Evaluate the 2500Vrms isolation strength relative to the circuit's safety clearance needs. Compare the 8-pin surface-mount package dimensions against available board space limitations.

Part Context

This part belongs to the IL711 family of digital isolators designed for general-purpose applications. The series integrates logic functions within the isolation barrier, reducing external component count. The IL 711-1ETR7 variant specifically denotes the reel-packaged version of the standard IL 711-1E device, maintaining identical electrical characteristics while optimizing for SMT production lines.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs before considering alternative manufacturers, as GMR technology differs significantly from capacitive or optical isolation methods.
