SN74AHCT1G04DCKR

Texas Instruments · Inverters · SC-70-5

SN74AHCT1G04DCKR from Texas Instruments, in a SC-70-5. 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 a static level; the pin has no electrical function inside the device.
2 A input Logic input A to the inverter. TTL-voltage compatible: VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Output Y is the logical inversion of this input.
3 GND power_in Device ground reference (0 V). All input/output voltages are referenced to this pin.
4 Y output Inverter output Y = /A. Push-pull CMOS output rated ±8 mA drive at VCC = 5 V (IOH = -8 mA, IOL = 8 mA); VOH ≥ 3.94 V typ and VOL ≤ 0.36 V typ at 4.5 V.
5 VCC power_in Positive supply pin. Recommended operating range 4.5 V to 5.5 V (absolute max 7 V). Decouple to GND with a 0.1 µF ceramic capacitor close to the device.

Ordering variants

Same part, different packaging or reel option.

  • SN74AHCT1G04DCKR

CAD (KiCad official)

  • Symbol: SN74AHCT1G04DCKR
  • Footprint: Package_TO_SOT_SMD:SOT-353_SC-70-5
  • 3D model: SC-70-5 (KiCad packages3D, STEP)
  • 3D model files: sn74ahct1g04dckr-etched.step / sn74ahct1g04dckr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ahct1g04dckr.step / sn74ahct1g04dckr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahct1g04dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74ahct1g04dckr-etched.step 2.5 MB You want the part with SN74AHCT1G04DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 641 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 (24 pp, sha256 05199cf2c623cc8b, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
