The IL3085 is a galvanically isolated, high-speed differential bus transceiver, designed for bidirectional data communication on balanced transmission lines. The device uses NVE’s patented* IsoLoop spintronic Giant Magnetoresistance (GMR) technology.
A unique ceramic/polymer composite barrier provides excellent isolation and virtually unlimited barrier life.
The wide-body version provides true 8 mm creepage. Narrow-body and QSOP packages offer unprecedented miniaturization.
The IL3085 delivers at least 1.5 V into a 27 Ω load for excellent data integrity over long cable lengths. The device is compatible with 3.3 V input supplies, allowing interface to standard microcontrollers without additional level shifting.
Current limiting and thermal shutdown features protect against output short circuits and bus contention that may cause excessive power dissipation. Receiver inputs feature a “fail-safe if open” design, ensuring a logic high R-output if A/B are floating.
