| 4 | H | output | Inverting output 2, produces logic inverse of input B. |
| 5 | B | input | Digital logic input 2 for second inverting buffer stage. |
| 6 | I | output | Inverting output 3, produces logic inverse of input C. |
| 7 | C | input | Digital logic input 3 for third inverting buffer stage. |
| 8 | VSS | power_in | Ground and negative power supply reference. |
| 9 | D | input | Digital logic input 4 for fourth inverting buffer stage. |
| 10 | J | output | Inverting output 4, produces logic inverse of input D. |
| 11 | E | input | Digital logic input 5 for fifth inverting buffer stage. |
| 12 | K | output | Inverting output 5, produces logic inverse of input E. |
| 13 | NC | unconnected | No connection; internally unconnected pin. |
| 14 | F | input | Digital logic input 6 for sixth inverting buffer stage. |
| 15 | L | output | Inverting output 6, produces logic inverse of input F. |
| 16 | NC | unconnected | No connection; internally unconnected pin. |

## CAD (KiCad official)

- Symbol: `CD4049UBE`
- Footprint: `Package_DIP:DIP-16_W7.62mm`
- 3D model: DIP-16 (KiCad packages3D, STEP)
- 3D model files: `cd4049ube-etched.step` / `cd4049ube-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `cd4049ube.step` / `cd4049ube.glb` are the bare package body.
