Description
IL800-Series isolators are high-speed, high temperature dc-correct
isolators. An internal refresh clock ensures the outputs respond to dc states on
inputs within a maximum of 9 µs.
IL814
IL817
The devices use NVE’s patented* spintronic Giant Magnetoresistive
(GMR) technology.
A unique ceramic/polymer composite barrier provides excellent isolation
and virtually unlimited barrier life.
