CAD (KiCad official)

  • Symbol: CY4N35
  • Footprint: Package_DIP:DIP-6_W7.62mm
  • 3D model: DIP-6 (KiCad packages3D, STEP)
  • 3D model files: cy4n35-etched.step / cy4n35-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cy4n35.step / cy4n35.glb are the bare package body.
