SN74AHCT1G04DBVR

Texas Instruments · Inverters · SOT-23-5

SN74AHCT1G04DBVR 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. Pin may be left floating or tied to VCC/GND for mechanical stability.
2 A input Logic input A. TTL-voltage compatible CMOS input (VIH ≥ 2 V, VIL ≤ 0.8 V at VCC = 4.5-5.5 V). Output Y is the logical inverse of this pin.
3 GND power_in Ground reference. Must be connected to the system 0 V rail.
4 Y output Logic output Y = /A. Push-pull CMOS output rated ±8 mA at VCC = 5 V (VOH ≥ 3.94 V, VOL ≤ 0.36 V).
5 VCC power_in Supply voltage input. Recommended operating range 4.5 V to 5.5 V (absolute max 7 V). Bypass with a 0.1 µF ceramic capacitor placed close to the pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahct1g04dbvr.step 85 KB You want the bare part, or you mark your own boards.
sn74ahct1g04dbvr-etched.step 2.3 MB You want the part with SN74AHCT1G04DBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 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).
