IL 611-3ETR7

Overview

The IL 611-3ETR7 is a general-purpose digital isolator manufactured by NVE Corp/Isolation Products. It features two channels with a unidirectional input configuration (2/0). The device utilizes capacitive coupling technology and operates within a supply voltage range of 3V to 5.5V. It provides 2500Vrms isolation voltage and supports data rates up to 1Mbps. The component has a maximum propagation delay of 475ns and a typical rise/fall time of 2ns. It is housed in an 8-SOIC package and functions within a temperature range of -40°C to 85°C.

Feature Summary

• Provides galvanic isolation between circuits using capacitive coupling technology
• Features passive input design with CMOS outputs for enhanced performance over optocouplers
• Supports high-speed data transmission while maintaining signal integrity

Applications

• General-purpose digital isolation
• Circuit isolation between power domains
• Signal transmission across isolated boundaries

Procurement Notes

Verify the manufacturer designation as NVE Corp/Isolation Products or simply NVE when sourcing this component. Confirm the specific suffix 'ETR7' corresponds to the tape and reel packaging format required for your assembly line. Ensure the datasheet matches the current revision, as part numbers may undergo updates or supersessions that affect pinout or electrical characteristics without changing the base model number.

Selection Notes

Select this component when a passive input digital isolator is required to replace traditional optocouplers. It is suitable for applications needing bidirectional or unidirectional signal transfer with moderate speed requirements. Consider the 8-SOIC package size for space-constrained designs. Verify that the 2500Vrms isolation rating meets the safety standards of the target application environment.

Part Context

The IL 611 series belongs to NVE's portfolio of digital isolators designed to offer improved circuit performance compared to conventional optocoupler solutions. These devices are engineered to withstand significant voltage differences between separate power domains. The family focuses on providing reliable signal transmission with lower power consumption and higher reliability than legacy isolation technologies.

Replacement Considerations

Public confirmed substitute part numbers include IL 715-3ETR7 and IL 717ETR13 from NVE Corp/Isolation Products. Cross-reference tools indicate parametrically similar parts from other manufacturers such as Texas Instruments ISO7220ADR and Analog Devices ADUM1200CRZ-RL7, though interface and speed specifications should be verified against the original design requirements.
