The 70 mV of receiver hysteresis gives you real noise margin on long cable runs — it won't chatter on a 100-metre bus with a few volts of common-mode noise riding on the signal.
Industrial temperature grade — where this transceiver lives
The 125°C ceiling covers the hot side of a sealed enclosure next to a motor drive or a power supply. If your design lives in a climate-controlled server room, the extended range is headroom you don't have to derate.
Package and footprint — 10-VSSOP
Housed in a 10-VSSOP (3.00 mm × 3.00 mm body), it's a compact surface-mount part that fits on tight mixed-signal boards.
