SN74LVC1G38DCKR

Texas Instruments · Gates · SC-70-5

SN74LVC1G38DCKR 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 A input Logic Input A of the 2-input NAND gate. Accepts input voltages up to 5.5V regardless of VCC (supports down-translation).
2 B input Logic Input B of the 2-input NAND gate. Accepts input voltages up to 5.5V regardless of VCC (supports down-translation).
3 GND power_in Ground reference (0V).
4 Y output Open-drain NAND output, Y = NOT(A AND B). Requires an external pull-up resistor to a supply up to 5.5V. Sinks up to 32 mA at VCC=4.5V (VOL=0.55V).
5 VCC power_in Positive supply. Recommended operating range 1.65V to 5.5V; data retention down to 1.5V.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74lvc1g38dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74lvc1g38dckr-etched.step 2.6 MB You want the part with SN74LVC1G38DCKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 644 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 (41 pp, sha256 03684e6e8e08cafd, 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).
