The IL261-3E high speed digital isolator from NVE is a five channel CMOS device with typical data rate of 110Mbps. They feature working voltage of 600VRMS and isolation voltage of 2.5kVrms. The IL261-1E is available in 0.15″ 16-pin SOIC package, specified over a temperature range of −40°C to +85°C. These isolators are manufactured with NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology. The IL261-3E features symmetric magnetic coupling barrier, providing the best specification in terms of propagation delay and pulse width distortion on the market. The unique fifth channel can be used to distribute isolated clocks or handshake signals to multiple delta-sigma A/D converters. The unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL261 series, including IL261-3E is UL1577 recognised and certified to VDE 0884-10.
