2 1Y output Channel 1 inverter output Y = /1A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
3 2A input Channel 2 inverter input A. CMOS logic input; do not leave floating.
4 2Y output Channel 2 inverter output Y = /2A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
5 3A input Channel 3 inverter input A. CMOS logic input; do not leave floating.
6 3Y output Channel 3 inverter output Y = /3A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
7 GND power_in Device ground reference (0 V).
8 4Y output Channel 4 inverter output Y = /4A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
9 4A input Channel 4 inverter input A. CMOS logic input; do not leave floating.
10 5Y output Channel 5 inverter output Y = /5A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
11 5A input Channel 5 inverter input A. CMOS logic input; do not leave floating.
12 6Y output Channel 6 inverter output Y = /6A. Push-pull CMOS output rated +/-24 mA at VCC = 4.5 V.
13 6A input Channel 6 inverter input A. CMOS logic input; do not leave floating.
14 VCC power_in Positive supply, 2 V to 6 V recommended (7 V absolute max). Bypass with a 0.1 uF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

  • Symbol: SN74AC04DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: sn74ac04dr-etched.step / sn74ac04dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sn74ac04dr.step / sn74ac04dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ac04dr.step 195 KB You want the bare part, or you mark your own boards.
sn74ac04dr-etched.step 2.2 MB You want the part with SN74AC04DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 574 faces against 237 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 (39 pp, sha256 3f34f59f447bb007, 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).
