At that speed on a typical twisted-pair run, the cable length is limited to a few metres before signal degradation sets in — this part is sized for short-haul, high-throughput links inside a cabinet or backplane, not kilometre-long fieldbus drops. The 80 mV receiver hysteresis cleans up noise on the differential pair, which helps maintain margin at the higher bit rate.
Half duplex. The single driver and single receiver share the same bus pair, so the software must manage direction control via the driver enable pin.
