The Texas Instruments SN65HVD34DRG4 is a full-duplex transceiver supporting both RS-422 and RS-485 protocols in a single 14-SOIC package. The 50 mV of receiver hysteresis provides noise immunity on long cable runs without external biasing.
The base electrical design is the same — both are full-duplex RS-485/RS-422 transceivers with 5 Mbps data rate and 3V–3.6V supply. The SN65HVD34DRG4 uses the 'RG4' suffix which indicates a specific tape-and-reel packaging option (not a functional difference). Pin-compatible and electrically identical for the same operating conditions.
