Introduction

NVE’s IL700 family of high-speed digital isolators are CMOS devices 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 symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion as low as 300 ps (0.3 ns), achieving the best specifications of any isolator. Minimum transient immunity of 100 kV/μs is unsurpassed. The IL710 is ideal for isolating applications such as PROFIBUS, RS-485, and RS-422. The IL710 is available in 8-pin MSOP, SOIC, and PDIP packages. The IL710S is the fastest isolator of its type, with a 150 Mbps typical data rate. Standard and S-Grade parts are specified over a temperature range of -40°C to +100°C. T-Grade parts are specified over a temperature range of -40°C to +125°C. The MSOP V-Series version offers full 2500 VRMS isolation in an ultraminiature package.
