Texas Instruments · Inverters · SOIC-14

SN74HCT04DR from Texas Instruments, in a SOIC-14. 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 1A input Inverter 1 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V. Input hold current ±100 nA typ.
2 1Y output Inverter 1 output (Y = /1A). Push-pull output; drives ±4 mA at V_CC = 5 V (10 LSTTL loads).
3 2A input Inverter 2 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V.
4 2Y output Inverter 2 output (Y = /2A). Push-pull output; drives ±4 mA at V_CC = 5 V.
5 3A input Inverter 3 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V.
6 3Y output Inverter 3 output (Y = /3A). Push-pull output; drives ±4 mA at V_CC = 5 V.
7 GND power_in Ground reference (0 V). Continuous current through GND ≤ 50 mA.
8 4Y output Inverter 4 output (Y = /4A). Push-pull output; drives ±4 mA at V_CC = 5 V.
9 4A input Inverter 4 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V.
10 5Y output Inverter 5 output (Y = /5A). Push-pull output; drives ±4 mA at V_CC = 5 V.
11 5A input Inverter 5 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V.
12 6Y output Inverter 6 output (Y = /6A). Push-pull output; drives ±4 mA at V_CC = 5 V.
13 6A input Inverter 6 input. TTL-compatible logic input; V_IH ≥ 2 V, V_IL ≤ 0.8 V at V_CC = 4.5-5.5 V.
14 VCC power_in Positive supply voltage, 4.5 V to 5.5 V (nom 5 V). Requires 0.1-µF bypass capacitor close to the pin. Absolute max 7 V.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74hct04dr.step 195 KB You want the bare part, or you mark your own boards.
sn74hct04dr-etched.step 2.3 MB You want the part with SN74HCT04DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 594 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 (29 pp, sha256 efe8f799e2c8eb98, 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).
