If your design lives inside a conditioned panel, the temperature margin is comfortable. The 10 Mbps data rate supports Profibus and similar fieldbus segments at practical cable lengths — expect clean eye diagrams up to a few hundred meters at lower baud rates. For 10 Mbps full-speed runs, keep the stub length short and terminate properly.
The base product number 65HVD485 covers the same transceiver core. The EDG4 suffix indicates the specific 8-SOIC package variant and the RoHS-compliant 'G4' designation. Functionally they are identical for the same package option.
Within TI's own family, the SN65HVD485ED is the direct equivalent in the same 8-SOIC footprint. For a second-source option, the MAX485 or SP485 families offer similar half-duplex RS-485 transceivers in the same pinout, though verify supply range and data rate against your specific timing budget.
