The IL814T-1E high temperature, DC correct, high speed digital isolator from NVE is rated with an isolation voltage of 2.5kV_rms and 600V_rms working voltage per VDE V 0884-10, these isolators are available in an ultraminiature 16-pin QSOP package and are specified over a temperature range of −40°C to +125°C. IL800 series are industry’s top-of-the-line isolators with the best specification within their class. They are manufactured with NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology and featuring an internal refresher clock to ensure response to DC states of input within 9μs maximum. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life.
