Description

The IL3422E high speed passive input RS-422 isolated transceiver from NVE is designed to galvanically isolate bidirectional data communication over balanced transmission lines. The IL3422 series delivers at least 2V into a 100Ω 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 passive input RS-422 isolated transceiver
  • Power supply VDD1 between 3.3V and 5V, VDD2 between 4.5V and 5V
  • Data rate of 20Mbps
  • Bus ESD protection of 15kV
  • Isolation of 2,500VRMS (1 minute)
  • Temperature range of −40°C to +85°C
  • Typical common mode rejection 20kV/μs
  • No carrier or clock for low EMI emissions and susceptibility
  • Thermal shutdown protection
  • Propagation delay of 50ns (5V)
  • Coil resistance of 85Ω
  • UL 1577 recognised; IEC 60747-5-5 (VDE 0884) certified
  • 0.3″ 16-pin SOIC package

The IL3422 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 IL3422 series include:

  • Data loggers
  • P.O.S. systems
  • Security networks
  • Building environmental controls
  • Industrial control networks
  • Factory automation
