Introduction

Four-channel high-speed digital isolators are CMOS devices manufactured with patented IsoLoop spintronic Giant Magnetoresistive (GMR) technology. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. All transmit and receive channels operate at 110 Mbps over the full temperature and supply voltage range. The symmetric magnetic coupling barrier provides a typical propagation delay of only 10 ns and a pulse width distortion of 2 ns, achieving the best specifications of any isolator. Minimum transient immunity of 100 kV/μs is unsurpassed. High channel density makes these devices ideal for isolating ADCs and DACs, parallel buses and peripheral interfaces. The isolators are available in 16-pin 0.3" and 0.15" SOIC, and ultraminiature QSOP packages. Performance is specified over a temperature range of -40 °C to +100 °C. “T” and “V” Series parts have a maximum operating temperature of 125 °C V-Series versions have an extremely high isolation voltage of 6 kVRMS.
