High Speed digital isolators

The IL716E high speed digital isolator from NVE is a four channel CMOS device with typical data rate of 110Mbps. It features an isolation voltage of 2.5kV_rms and 600 V_rms working voltage per VDE V 0884-10. The IL716E isolators are available in an 16-pin SOIC package and are specified over a temperature range of −40°C to +100°C. These isolators are the industry standard for solid-state signal isolation and the ultimate in usable data rate and performance. The IL716E series from NVE are manufactured with NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL716 series, including IL716E is UL1577 recognised and certified to VDE V 0884-10.
