SN74AHC1G32DCKR

Texas Instruments · Gates · SC-70-5

SN74AHC1G32DCKR 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 OR gate. CMOS input with Schmitt-trigger action; V_IH from 1.5 V (V_CC=2 V) to 3.85 V (V_CC=5.5 V). Input leakage ±0.1 µA typ.
2 B input Logic Input B of the 2-input OR gate. CMOS input with Schmitt-trigger action; V_IH from 1.5 V (V_CC=2 V) to 3.85 V (V_CC=5.5 V). Input leakage ±0.1 µA typ.
3 GND power_in Ground reference for the device. Connect to the system ground plane.
4 Y output OR gate output, Y = A + B. Push-pull CMOS output rated ±8 mA at V_CC = 5 V (±4 mA at V_CC = 3.3 V). Propagation delay 6.5 ns max at 5 V.
5 VCC power_in Supply voltage input, 2 V to 5.5 V. Quiescent supply current I_CC = 10 µA max. Decouple with a 0.1 µF ceramic to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ahc1g32dckr.step 87 KB You want the bare part, or you mark your own boards.
sn74ahc1g32dckr-etched.step 2.6 MB You want the part with SN74AHC1G32DCKR 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 (26 pp, sha256 61cc1c2d734eb534, 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).
