The 50 mV of receiver hysteresis cleans up noise on long cable runs — a practical margin for factory-floor or outdoor telecom links where common-mode noise rides the bus.
The 14-SOIC footprint (3.90 mm width) is a standard industrial package; no tight-pitch rework required.
The SN65HVD55DRG4 supports a data rate of 1 Mbps.
Yes, it is a full-duplex transceiver, meaning it can transmit and receive simultaneously over separate differential pairs.
The SN65HVD55DRG4 and SN65HVD55DR are functionally identical transceivers. The 'G4' suffix indicates a lead-free (RoHS) and halogen-free version, while the 'DR' suffix indicates the standard tape-and-reel packaging. Both share the same electrical specs, pinout, and package.
