WS3080 from GEC EESA, in a MSOP-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	RO	output	Receiver output. When receiver is enabled (RE low): if V(A)-V(B) > -50mV, RO outputs high; if V(A)-V(B) < -200mV, RO outputs low. High-impedance when receiver disabled.
2	RE	input	Receiver output enable (active-low). When RE is low, RO is enabled. When RE is high, receiver is disabled. With RE high and DE low, the chip enters shutdown state.
3	DE	input	Driver output enable (active-high). When DE is high, the driver outputs are enabled. When DE is low, the driver outputs go high-impedance. With RE high and DE low, the chip enters shutdown state.
4	DI	input	Driver input. When DI is low, non-inverting output (A) is forced low and inverting output (B) is forced high. When DI is high, A is high and B is low.
5	GND	power_in	Ground reference (0V).
6	A	bidirectional	RS-485/RS-422 bus interface pin. Driver non-inverting output and receiver non-inverting input. Bus voltage range -8V to +13V; ±15kV HBM ESD protection.
7	B	bidirectional	RS-485/RS-422 bus interface pin. Driver inverting output and receiver inverting input. Bus voltage range -8V to +13V; ±15kV HBM ESD protection.
8	VCC	power_in	Positive supply, 4.75V to 5.25V (typ 5V). Bypass with a 0.1µF ceramic capacitor to GND. Absolute maximum 7V.

CAD (KiCad official)

Symbol: WS3080
Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
3D model: MSOP-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`ws3080.step`	123 KB	You want the bare part, or you mark your own boards.
`ws3080-etched.step`	1.9 MB	You want the part with `WS3080` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 459 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.
