The IL3585VE high isolation voltage, high speed differential input RS-485 isolated transceiver from NVE is designed to galvanically isolate bidirectional data communication over balanced transmission lines. The IL3585 series delivers at least 2.3V into a 54Ω load for excellent data integrity over long cables, and is also compatible with 3V input supplies, allowing interfacing to standard microcontrollers without additional level shifting. 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 0.3" 16-pin SOIC package.

  • Surface-mount high speed, galvanically isolated RS-485 transceiver

  • Data rate as high as 40Mbps
  • 15kV bus ESD protection
  • Isolation of 6kVRMS /12.8kV surge/1kVRMS WV
  • Operating temperature range of −40°C to +85°C
  • Typical common mode transiend immunity of 50kV/μs (30kV/μs typical)
  • Propagation delay as low as 20ns
  • Thermal shutdown protection
  • UL 1577 recognised; VDE V 0884-10 certified
  • 0.3" 16-pin SOIC package

The IL3585 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 IL3585 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
