Description
The IL485 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
IL485 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 IL485 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 IL485 is ideal
for PROFIBUS applications.
