The IL261E high speed digital isolator from NVE is a five channel CMOS device with typical data rate of 110Mbps. They feature working voltage of 600V_RMS and isolation voltage of 2.5kV_rms. The IL261E is available in an 16-pin 0.3″ 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 IL261E 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 IL261E is UL1577 recognised and certified to VDE 0884-10.
