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

SN74AHCT1G02DBVR

Texas Instruments · Gates · SOT-23-5

SN74AHCT1G02DBVR 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 A input Logic input A of the 2-input NOR gate. TTL-voltage compatible (VIH min 2 V, VIL max 0.8 V). Input clamp current limited to -20 mA per absolute maximum ratings.
2 B input Logic input B of the 2-input NOR gate. TTL-voltage compatible (VIH min 2 V, VIL max 0.8 V). Unused inputs must be tied to VCC or GND.
3 GND power_in Ground reference pin (0 V). Return for VCC supply current and all logic-low output current.
4 Y output NOR gate output, Y = NOT(A OR B). Push-pull CMOS output with ±8 mA drive at 5 V. VOH ≥ 3.8 V and VOL ≤ 0.44 V at IO = ±8 mA, VCC = 4.5 V.
5 VCC power_in Positive supply voltage input, 4.5 V to 5.5 V recommended (7 V absolute max). ICC ≤ 10 µA quiescent. Bypass with a 0.1 µF ceramic capacitor placed close to the pin.

CAD (KiCad official)

  • Symbol: SN74AHCT1G02DBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: sn74ahct1g02dbvr-etched.step / sn74ahct1g02dbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ahct1g02dbvr.step / sn74ahct1g02dbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahct1g02dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74ahct1g02dbvr-etched.step 2.4 MB You want the part with SN74AHCT1G02DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 613 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.
