The receiver hysteresis is specified at 80 mV, which gives a clean logic transition on long or heavily loaded RS-485 buses where ground shifts and cable reflections eat into the differential signal. That margin matters when the cable run exceeds a few hundred feet or passes near variable-frequency drives.
The logic inputs and outputs are 3.3V-compatible within that supply window.
Both are half-duplex RS-485 transceivers from TI in the same 8-SON package. The SN65HVD75DRBR is rated for 20 Mbps, while the SN65HVD72DRBR is a lower-speed variant typically specified at 250 kbps. The faster part is the choice for high-throughput links; the slower one saves a few cents per unit on a low-speed fieldbus.
