## CAD (KiCad official)
- Symbol: `74LVX3245MTCX`
- Footprint: `Package_SO:TSSOP-24_4.4x7.8mm_P0.65mm`
- 3D model: TSSOP-24 (KiCad packages3D, STEP)
- 3D model files: `74lvx3245mtcx-etched.step` / `74lvx3245mtcx-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `74lvx3245mtcx.step` / `74lvx3245mtcx.glb` are the bare package body.
