IL821T-3E

Digital Isolators Overview

The IL821T-3E is a high-speed, DC-correct digital isolator manufactured by NVE. It features two independent channels supporting bidirectional data transmission at rates up to 110 Mbps. The device provides galvanic isolation with a rating of 2500 Vrms and a common-mode transient immunity (CMTI) of 30 kV/µs. It operates within an extended temperature range up to 125 °C and is housed in an 8-pin SOIC package.

Digital Isolators Feature Summary

• Provides deterministic galvanic isolation using spintronic technology
• Supports high-speed bidirectional data transmission up to 110 Mbps
• Ensures signal integrity with DC-correct architecture

Digital Isolators Applications

• RS422 communication interfaces
• RS485 communication interfaces
• Industrial control systems requiring high noise immunity

Digital Isolators Procurement Notes

Verify the specific suffix '3E' against official NVE documentation to confirm voltage levels and pinout configurations. Ensure the selected component matches the required operating temperature range of 125 °C for your application environment. Cross-reference the datasheet specifications for CMTI and isolation ratings to validate suitability for high-noise industrial settings.

Digital Isolators Selection Notes

Select this component when high-speed data transfer is required alongside robust galvanic isolation. The 110 Mbps rate supports standard industrial protocols like RS422 and RS485. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the 30 kV/µs CMTI meets the noise rejection requirements of the target system.

Digital Isolators Part Context

NVE specializes in spintronic solutions, leveraging Giant Magnetoresistive (GMR) technology for isolation products. The IL821T-3E belongs to the IL800 series, designed for applications demanding high reliability and speed. This series utilizes magnetic coupling rather than optical or capacitive methods, offering distinct advantages in longevity and performance stability.
