Receiver Features
The receiver includes a “fail-safe if open” function that guarantees a high level output if the receiver inputs are unconnected (floating). The
receiver output “R” has tri-state capability via the active low RE input.
Driver Features
The RS-422 driver is differential output and delivers at least 1.5 V across a 54 load. 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
The IL3522 is intended for networks up to 4,000 feet (1,200 m), but the maximum data rate decreases as cable length increases. Twisted pair
cable should be used in all networks since they tend to pick up noise and other electromagnetically induced voltages as common mode signals,
which are effectively rejected by the differential receivers.
