NVE IL612-2E

The IL612-2E passive input digital isolator from NVE is a two channel signal coupler with flexible, wide range of input voltage and CMOS output. This isolator features data rate of 100Mbps, working voltage of 300V_RMS and endures high voltage of 1kV_rms/1.5kVdc. The IL612-2E is available in an 8-pin PDIP package, specified over a temperature range of −40°C to +85°C. The IL612 series from NVE are a passive input digital isolator CMOS 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 IL612 series, including IL612-2E is UL1577 recognised and certified to IEC 60747-5-5 (VDE 0884).
