The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

SN74AHCT1G14DBVR

Texas Instruments · Inverters · SOT-23-5

SN74AHCT1G14DBVR from Texas Instruments, in a SOT-23-5. 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 NC unconnected No internal connection. Leave floating or tie to VCC/GND per board convention.
2 A input Data input to the Schmitt-trigger inverter. TTL-compatible input with hysteresis (typ VT+ ≈ 1.6 V, VT- ≈ 1.1 V at VCC = 5 V). Input voltage range 0 to 5.5 V; must not be left floating.
3 GND power_in Ground reference (0 V) for the device.
4 Y output Inverted data output (Y = A̅). Push-pull CMOS output rated ±8 mA at VCC = 5 V; VOH ≥ 3.94 V @ IOH = -8 mA, VOL ≤ 0.36 V @ IOL = 8 mA (VCC = 4.5 V).
5 VCC power_in Positive supply voltage. Recommended operating range 4.5 V to 5.5 V; absolute maximum 7 V. Decouple with a 100 nF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

  • Symbol: SN74AHCT1G14DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sn74ahct1g14dbvr-etched.step / sn74ahct1g14dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ahct1g14dbvr.step / sn74ahct1g14dbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahct1g14dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74ahct1g14dbvr-etched.step 2.2 MB You want the part with SN74AHCT1G14DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 570 faces against 102 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: Texas Instruments datasheet (25 pp, sha256 5657941b4f3173e4, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
