CAD (KiCad official)

  • Symbol: 74HC74PW
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: 74hc74pw-etched.step / 74hc74pw-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74hc74pw.step / 74hc74pw.glb are the bare package body.
  • Laser-etched variant: 74hc74pw-etched.step / 74hc74pw-etched.glb, the same package body with the MPN marked on the die, in a toggleable Adom.LaserEtch group (Fusion-ready).
