SN65HVD3082EDR 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 (digital). Delivers the received differential bus data as a single-ended CMOS-level signal to the host UART/MCU.
2	RE	input	Receiver enable, active low. Drive low to enable the receiver output R; drive high to place R in high-impedance.
3	DE	input	Driver enable, active high. Drive high to enable the differential bus driver on A/B; drive low to place driver outputs in high-impedance.
4	D	input	Driver data input (digital). CMOS-level TX data from the host UART/MCU that is transmitted as a differential signal on A/B when the driver is enabled.
5	GND	power_in	Local device ground (reference potential, 0 V).
6	A	bidirectional	RS-485 differential bus I/O, non-inverting line. Driver output or receiver input, complementary to B. 15-kV ESD protected bus pin.
7	B	bidirectional	RS-485 differential bus I/O, inverting line. Driver output or receiver input, complementary to A. 15-kV ESD protected bus pin.
8	VCC	power_in	Positive supply input, 4.5 V to 5.5 V (5-V nominal). Bypass locally with a 100-nF ceramic to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn65hvd3082edr.step`	122 KB	You want the bare part, or you mark your own boards.
`sn65hvd3082edr-etched.step`	3.0 MB	You want the part with `SN65HVD3082EDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 729 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.
