The IL3022E low cost RS-485/RS422 isolated transceiver from NVE is designed to galvanically isolate bidirectional data communication over balanced transmission lines. The IL3022 series delivers at least 1.5V into a 27โ„ฆ 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 NVEโ€™s patented IsoLoop spintronic Giant Magnetoresistance (GMR) technology and comes in a 0.3โ€ณ 16-pin SOIC package.

  • Typical common mode rejection 50kV/ฮผs (30kV/ฮผs minimum)
  • Supports up to 32 nodes
  • Thermal shutdown protection
  • Typical propagation delay of 48ns (5V)
  • UL 1577 recognised; VDE V 0884-10 certified
  • 0.3โ€ณ 16-pin SOIC package

The IL3011E 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 โ€œfail-safe if openโ€ design, ensuring a logic high on R if the bus lines are disconnected or โ€œfloating.โ€

Typical applications for the IL3022 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
