IL 816T-3E

Overview

The IL816T-3E is a general-purpose digital isolator from NVE Corporation, utilizing True 8® GMR technology for signal transmission across an isolation barrier. It features four independent channels within a 16-pin SOIC package. The device supports a maximum data rate of 110Mbps and offers a common-mode transient immunity (CMTI) of 30kV/µs. It is rated for an isolation voltage of 2500Vrms and a working voltage of 600Vrms. Operating temperatures range from -40°C to +125°C, with a maximum input current of 10μA and a rise time of 4ns.

Feature Summary

• Utilizes Giant Magnetoresistance (GMR) technology for DC-correct signal processing
• Provides high common-mode transient immunity of 30kV/µs
• Supports operation in extended industrial temperature environments up to +125°C

Applications

• Industrial communication systems
• Embedded control applications
• IoT devices requiring small form factor designs

Procurement Notes

Verify the specific suffix 'T-3E' to confirm tape-and-reel packaging and temperature grade. Ensure the 16-SOIC footprint matches the target PCB layout. Confirm that the 2500Vrms isolation rating meets the safety requirements of the end application. Cross-reference the manufacturer's latest datasheet for any updates on RoHS compliance or material declarations before finalizing procurement.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust noise immunity. The 110Mbps data rate suits standard serial communication protocols. The 16-pin SOIC package facilitates surface-mount assembly. Consider the 30kV/µs CMTI for environments with rapid voltage switching. Verify compatibility with system voltage levels and thermal management needs for high-temperature operation.
