Description
The IL3085-3E low cost, galvanically isolated RS-485 transceiver from NVE offers data rate of 4Mbps and very low quiescent current. The IL3085 series delivers at least 1.5V into a 27Ω load for excellent data integrity over long cables, and is also compatible with 3V power supplies. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. This particular device uses NVE’s patented IsoLoop spintronic Giant Magnetoresistance (GMR) technology and comes in a 0.15″ 16-pin SOIC package.

The IL3085 has current limiting and thermal shutdown features to protect against output short circuits and bus contentions that may cause excessive power dissipation, and also incorporate a “fail-safe if open” design, ensuring a logic high on R if the bus lines are disconnected or “floating.”
Typical applications for the IL3085 series include:
- Factory automation
- Industrial control networks
- Building environmental controls
- Equipment covered under IEC 61010-1 Edition 3
- 5kVRMS rated IEC 60601-1 medical applications
