74HC14D

Nexperia · Inverters · SOIC-14

74HC14D from Nexperia, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1A input Schmitt-trigger data input to inverter 1. Typical VT+ ~2.38 V, VT- ~1.4 V at VCC=4.5 V; hysteresis ~0.98 V.
2 1Y output Inverting data output for channel 1. CMOS push-pull, capable of ±5.2 mA at VCC=6.0 V while maintaining valid levels.
3 2A input Schmitt-trigger data input to inverter 2.
4 2Y output Inverting data output for channel 2.
5 3A input Schmitt-trigger data input to inverter 3.
6 3Y output Inverting data output for channel 3.
7 GND power_in Ground reference (0 V).
8 4Y output Inverting data output for channel 4.
9 4A input Schmitt-trigger data input to inverter 4.
10 5Y output Inverting data output for channel 5.
11 5A input Schmitt-trigger data input to inverter 5.
12 6Y output Inverting data output for channel 6.
13 6A input Schmitt-trigger data input to inverter 6.
14 VCC power_in Positive supply voltage. Operating range 2.0 V to 6.0 V (74HC14); absolute max +7 V. Decouple with 100 nF close to the pin.

CAD (KiCad official)

  • Symbol: 74HC14D
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: 74hc14d-etched.step / 74hc14d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 74hc14d.step / 74hc14d.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
74hc14d.step 195 KB You want the bare part, or you mark your own boards.
74hc14d-etched.step 1.5 MB You want the part with 74HC14D already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 413 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Nexperia datasheet (16 pp, sha256 ab7028cdd8c5ce85, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
