Description
The IL422 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
IL422 is the first isolated RS-422 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 IL422 has current limiting and thermal shutdown features to
protect against output short circuits and bus contention situations that
could cause excessive power dissipation.
