High Speed digital isolators

The IL717VE high voltage, high speed digital isolator from NVE is a four channel CMOS device with typical data rate of 110Mbps. It features an isolation voltage of 6kV_rms and 1kV_rms working voltage per VDE V 0884-10. The IL717VE isolators are available in an 16-pin SOIC package and are specified over a high temperature range of −40°C to +125°C. These isolators are the industry standard for solid-state signal isolation and the ultimate in usable data rate and performance. The IL717VE 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 IL717 series, including IL717VE is UL1577 recognised and certified to VDE V 0884-10.
