At 10 Mbps the SN65HVD11DR keeps up with Profibus and similar fieldbus rates without stretching the bit timing. The half-duplex architecture requires the firmware to manage the driver enable pin; tie it to the UART's DE signal for automatic direction control. The 35 mV hysteresis is enough to prevent chatter on an idle bus with the fail-safe biasing, but if the cable runs past 100 metres at this rate, add external termination and TVS clamps on the bus pins.
Package and mounting — 8-SOIC footprint
The SN65HVD11DR comes in an 8-SOIC (3.90 mm width) package, surface-mount only. The 'DR' suffix indicates Tape & Reel or Cut Tape delivery. The 1.27 mm pin pitch is standard for SOIC-8, so the footprint matches any generic SOIC-8 land pattern. No thermal pad, no exposed paddle — just a straightforward two-layer board layout with a 0.1 µF decoupling cap near the supply pin.
No AEC-Q automotive qualification is listed, so keep it for industrial and commercial designs — not under-hood automotive.
