IL3685P
ENV50204 Radiated Field from Digital Telephones (Immunity Test) Immunity to external magnetic fields is even higher if the field direction is “end-to-end” (rather than to “pin-to-pin”) as shown in the diagram above.
Application Information
Receiver Features The receiver output “R” has tri-state capability via the active low RE input. Driver Features The RS-485 driver has a differential output and delivers at least 2.1 V across a 54 Ω load. In addition, unlike most other transceivers, IL3685-Series transceivers meet stringent PROFIBUS standards for maximum differential output voltage. Drivers feature low propagation delay skew to maximize bit width and minimize EMI. Drivers have tri-state capability via the active-high DE input. Receiver Data Rate, Cables and Terminations PROFIBUS Type A bus cable is recommended for high transmission speeds (more than 500 Kbps). Type B should only be used at low baud rates and low requirements on the network distances. IL3685-Series transceivers are intended for networks up to 4,000 feet (1,200 m) with Type A bus cable and proper termination. The maximum data rate decreases as cable length increases. 8 NVE Corporation 11409 Valley View Road, Eden Prairie, MN 55344-3617 Phone: (952) 829-9217 YouTube.com/NveCorporation ©NVE Corporation
