NVE IL485WE

The IL485WE isolated RS-485 interface with handshake from NVE is an industry-standard differential bus transciever, designed to galvanically isolate bidirectional data communication over balanced transmission lines. DE/ISODE and IN1/OUT1 allow isolated RTSAS and DTSAS
handshaking. The IL485 series is also compatible with 3V and 5V input supplies. The device uses NVE’s patented IsoLoop spintronic Giant
Magnetoresistance (GMR) technology and comes in a 0.3″ 16-pin SOIC package. IL485 was the first isolated RS-485 transciever in a standard 16-pin SOIC package to meed the ANSI Standards EIA/TIA-422-B and RS-485.

The IL485 series has current limiting and thermal shutdown features to protect against output short circuits and bus contentions that may cause excessive power dissipation.

Typical applications for the IL485 series include:

• PROFIBUS/RS-485 Systems
• Multiple data point transmission
