NVE IL611A-1E

The IL600A-Series are isolated signal couplers with open drain outputs. They have a similar interface but better performance and higher package density than optocouplers. The devices are manufactured with NVE’s patented spintronic Giant Magnetoresistive (GMR) technology for small size, high speed, and low power. A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. A resistor sets the input current; a capacitor in parallel with the current-limit resistor provides improved dynamic performance. These versatile components simplify inventory requirements by replacing a variety of optocouplers, functioning over a wide range of data rates, edge speeds, and power supply levels. The devices are available in MSOP, SOIC, and PDIP packages, as well as bare die.
