SN65HVD3082ED 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 from the RS-485 receiver; VOH ≥ 4 V, VOL ≤ 0.4 V at ±8 mA.
2	RE	input	Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance. Tying both RE=high and DE=low puts the device in low-power shutdown.
3	DE	input	Driver enable, active high. Drive high to enable the differential bus driver onto A/B; drive low to place the driver in high-impedance.
4	D	input	Driver data input. CMOS-level TTL-compatible logic input that sets the differential state of the A/B bus outputs when the driver is enabled. VIH ≥ 2 V, VIL ≤ 0.8 V.
5	GND	power_in	Local device ground / reference potential for the logic and supply.
6	A	bidirectional	RS-485 differential bus I/O, non-inverting side. Driver output or receiver input; complementary to B. Withstands −9 V to +14 V bus voltage and ±15 kV HBM ESD.
7	B	bidirectional	RS-485 differential bus I/O, inverting side. Driver output or receiver input; complementary to A. Withstands −9 V to +14 V bus voltage and ±15 kV HBM ESD.
8	VCC	power_in	Positive supply input, 4.5 V to 5.5 V (5 V nominal). Typical ICC is 425 µA with driver and receiver enabled and ~1 nA in shutdown.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd3082ed.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd3082ed-etched.step`	2.8 MB	You want the part with `SN65HVD3082ED` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 679 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.
