Description

The IL3085-1E 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 miniature QSOP package.

  • Surface-mount low-cost, galvanically isolated RS-485 transceiver
  • 3V and 5V power supplies
  • Data rate of 4Mbps
  • 7kV bus ESD protection
  • Isolation of 2.5kVRMS per UL 1577
  • Working voltage of 300VRMS per VDE V 0884-10
  • Temperature range of −40°C to +85°C
  • Typical common mode transiend immunity of 50kV/μs (30kV/μs minimum)
  • Supports up to 32 nodes
  • Thermal shutdown protection
  • UL 1577 recognised, VDE V 0884-10 certified; meets or exceeds ANSI RS-485 and ISO 8482:1987(E)
  • QSOP 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
