The devices use NVEs patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology. The wide-body version provides true 8 mm creepage. Narrow-body DE ISODE and QSOP packages offer unprecedented miniaturization. IL3685-Series transceivers are fully PROFIBUS compliant, D including the rigorous PROFIBUS differential output voltage specifications. A R B A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life. RE The device is compatible with 3 V as well as 5 V input supplies, IL3685 allowing interface to standard microcontrollers without additional level shifting. (wide-body) Current limiting and thermal shutdown features protect against V (A-B) DE RE R D Mode ID output short circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a fail-safe if open 200 mV L L H X Receive design, ensuring a logic high R-output if A/B are floating. 200 mV L L L X Receive 1.5 V H L H H Drive 1.5 V H L L L Drive X X H Z X Hi-Z R Open L L H X Receive IsoLoop is a registered trademark of NVE Corporation.
