That data rate suits high-throughput industrial links — Profibus, Modbus RTU at extended baud rates, or backplane serial buses where the 5V supply is already on the rail. Full-duplex means separate driver and receiver enable lines; the bus can transmit and receive simultaneously, which halves the cable count compared to half-duplex schemes that need a direction-control GPIO. The 30 mV receiver hysteresis provides built-in noise margin on long cable runs where common-mode shifts and reflections degrade signal quality. At 20 Mbps the transition time is tight — keep stub lengths under 300 mm and terminate at both ends with 120 Ω to match the characteristic impedance.
Supply rail and temperature grade — design-in constraints
If your system is 3.3 V only, you need a level translator or a different transceiver — the SN65HVD3086EDGSR is not compatible with 3.3 V logic on the supply side.
Package and footprint — 10-VSSOP
The mounting is surface-mount only. The base product number is 65HVD3086, so a 10-pin VSSOP variant is the only package option in this suffix.
