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 load. In addition, unlike most other transceivers, the IL3685
also meets 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 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.
