thvd1500dr.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

THVD1500DR

Texas Instruments · RS-485 / RS-422 ICs · SOIC-8

THVD1500DR 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 output driven from the differential bus receiver comparing A vs. B.
2 /RE input Receiver enable, active low. Internal ~2-MΩ pull-up; drive low to enable the receiver output on R.
3 DE input Driver enable, active high. Internal ~2-MΩ pull-down; drive high to enable the differential bus driver onto A/B.
4 D input Driver data input. Digital input carrying the TX data driven onto the A/B differential bus when DE is high.
5 GND power_in Local device ground reference (0 V).
6 A bidirectional RS-485/RS-422 differential bus I/O, non-inverting (complementary to B). Tolerates -18 V to 18 V absolute-max bus voltage and ±8-kV IEC contact discharge ESD.
7 B bidirectional RS-485/RS-422 differential bus I/O, inverting (complementary to A). Tolerates -18 V to 18 V absolute-max bus voltage and ±8-kV IEC contact discharge ESD.
8 VCC power_in Supply pin, 4.5 V to 5.5 V (5-V nominal). Bypass to GND with a low-ESR ceramic close to the pin.

Ordering variants

Same part, different packaging or reel option.

  • THVD1500DR
  • THVD1500DRD

CAD (KiCad official)

  • Symbol: THVD1500DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: thvd1500dr-etched.step / thvd1500dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); thvd1500dr.step / thvd1500dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
thvd1500dr.step 122 KB You want the bare part, or you mark your own boards.
thvd1500dr-etched.step 1.9 MB You want the part with THVD1500DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 490 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.
