ws3080.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

WS3080

GEC EESA · RS-485 / RS-422 ICs · MSOP-8

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.

Ordering variants

Same part, different packaging or reel option.

  • WS3080

CAD (KiCad official)

  • Symbol: WS3080
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ws3080-etched.step / ws3080-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ws3080.step / ws3080.glb are the bare package body.

3D model downloads

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.
