Description
The IL485W is a galvanically isolated, high-speed differential bus
transceiver, designed for bidirectional data communication on
balanced transmission lines. The devices use NVE’s patented*
IsoLoop spintronic Giant Magnetoresistance (GMR) technology. The
IL485W is the first isolated RS-485 interface in a standard 16-pin
SOIC package that meets the ANSI Standards EIA/TIA-422-B and
RS-485 and is compatible with 3.3V input supplies.
The IL485W has current limiting and thermal shutdown features to
protect against output short circuits and bus contention situations that
could cause excessive power dissipation.
With 1 ns pulse skew and 16 ns propagation delay, the IL485W is
ideal for PROFIBUS applications.
DE/ISODE and IN1/OUT1 allow isolated RTSAS and DTSAS
handshaking.

... IsoLoop Isolators achieve their low power consumption from the way they transmit data across the isolation barrier. By detecting the edge transitions of the input logic signal and converting these to narrow current pulses, a magnetic field is created around the GMR Wheatstone bridge. Depending on the direction of the magnetic field, the bridge causes the output comparator to switch following the input logic signal ...
