Supply range and bus compatibility
If you're feeding it from a 3.3V rail, you're in the sweet spot. The receiver hysteresis is specified at 100 mV, which gives the bus a clean noise margin on long twisted-pair runs — useful when the cable leaves the cabinet and picks up motor-drive hash.
No last-time-buy clock is ticking, and there's no immediate need to qualify a drop-in replacement for a new design. That said, the base product number is 65HVD230, and the 'MDREP' suffix denotes the military temperature range and enhanced-product (EP) qualification — a different tier from the commercial 65HVD230D.
