Description
The IL3685 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.
The IL3685 is fully PROFIBUS compliant, including the rigorous
PROFIBUS differential output voltage specifications.
The device is compatible with 3.3 V as well as 5 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.
