NVE IL611A-3E

The IL611A-3E passive input digital isolator from NVE is a two channel signal coupler with flexible, wide range of input voltage and open drain output. This isolator features data rate of 10Mbps, working voltage of 150V_RMS and endures high voltage of 1kV_rms/1.5kVdc. The IL611A-2E is available in an 16-pin 0.15″ SOIC package, specified over a temperature range of −40°C to +85°C. The IL611A series from NVE are a passive input digital isolator devices manufactured with NVE’s patented IsoLoop® spintronic Giant Magnetoresistive (GMR) technology. They have a similar interface but better performance than optocouplers, featuring a higher package density and functioning over a wide range of data ranges, edge speeds and power supply levels. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. The IL611A series, including IL611A-3E is UL1577 recognised and certified to IEC 60747-5-5 (VDE 0884).
