SN65HVD10DR from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	R	output	Receive data output. CMOS-level digital output reflecting the state of the differential bus (A-B). High-level output current -60 mA (max), low-level output current 8 mA (max). Driven only when the receiver is enabled (RE low).
2	RE	input	Active-low receiver enable. Drive low to enable the receiver output R; drive high to place R in a high-impedance state. Combined with DE=low, places the device in low-current standby mode (typ 1 µA).
3	DE	input	Active-high driver enable. Drive high to enable the differential driver onto the A/B bus; drive low to place the driver outputs in a high-impedance state. Combined with RE=high, places the device in standby.
4	D	input	Driver data input. CMOS-level logic input whose state determines the polarity of the differential signal driven onto A/B when DE is high. VIH ≥ 2 V, VIL ≤ 0.8 V.
5	GND	power_in	Local device reference potential (ground return).
6	A	bidirectional	Non-inverting RS-485 bus I/O pin. Driver output or receiver input (complementary to B). Withstands -7 V to 12 V bus common-mode range and ±16-kV HBM ESD. Absolute-max continuous voltage -9 V to 14 V.
7	B	bidirectional	Inverting RS-485 bus I/O pin. Driver output or receiver input (complementary to A). Withstands -7 V to 12 V bus common-mode range and ±16-kV HBM ESD. Absolute-max continuous voltage -9 V to 14 V.
8	VCC	power_in	Positive supply. Recommended 3.0 V to 3.6 V (nominal 3.3 V). Standby supply current typically 1 µA when both driver and receiver are disabled.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd10dr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd10dr-etched.step`	2.2 MB	You want the part with `SN65HVD10DR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 552 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
