Interface integration note
The 10 Mbps data rate supports fast fieldbus links such as PROFIBUS-DP and motion-control networks, while the 50 mV receiver hysteresis provides noise margin on long cable runs typical in factory-floor installations.

Frequently asked questions
What is the closest pin-compatible alternative to the SN65HVD1782DR?
Within the same base family (65HVD178x), other variants differ primarily by data rate and fault protection level; for a drop-in replacement, check the SN65HVD1781D (lower data rate) or SN65HVD1785D (higher ESD rating) — both share the same 8-SOIC footprint and pinout.
