CAD (KiCad official)

  • Symbol: SN65HVD22DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: sn65hvd22dr-etched.step / sn65hvd22dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn65hvd22dr.step / sn65hvd22dr.glb are the bare package body.
