IL 511-3E

Overview

The IL511-3E is a dual-channel digital isolator from NVE Corp/Isolation Products. It provides 2500Vrms isolation voltage with a data rate of up to 2Mbps and common-mode transient immunity of 30kV/µs. The device operates within an extended temperature range of -40°C to 85°C. It is housed in an 8-SOIC package with a width of 0.154 inches (3.90mm). This component utilizes NVE's patented technology for low-cost isolation.

Feature Summary

• Dual-channel configuration for general-purpose digital isolation
• High common-mode transient immunity capability
• Extended operating temperature range suitable for industrial environments

Applications

• General-purpose digital isolation circuits
• Industrial automation systems requiring signal isolation
• Low-cost alternatives to opto-couplers in data transmission

Procurement Notes

Verify the exact part number IL511-3E against official NVE documentation to ensure compatibility. Confirm that the 8-SOIC package dimensions match your PCB layout requirements. Check for any specific ordering suffixes or tape-and-reel options if available in current manufacturer catalogs.

Selection Notes

Select this component when dual-channel isolation is required at speeds up to 2Mbps. Consider its 30kV/µs CMTI rating for noisy environments. Ensure the 8-SOIC footprint fits the design constraints. Compare performance against other NVE series like IL500 or IL521 if higher channel counts or different voltage ratings are needed.

Part Context

The IL511-3E belongs to the IL500-series family of DC-correct digital isolators. These devices are designed as cost-effective replacements for traditional opto-couplers. The series leverages proprietary sensor technology to provide reliable signal transmission across isolation barriers without the limitations of LED-based components.

Replacement Considerations

IL510-3E serves as a single-channel variant within the same series. IL521-3E offers similar specifications but may differ in specific electrical characteristics or packaging details. Verify pinout compatibility before substituting.
