Texas Instruments · Inverters · SOIC-14

SN74LS06DR 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 Channel 1 inverter input. TTL-compatible logic input, VIH >= 2 V, VIL <= 0.8 V.
2 1Y output Channel 1 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA (SN74LS06). Requires external pull-up resistor.
3 2A input Channel 2 inverter input. TTL-compatible logic input.
4 2Y output Channel 2 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA.
5 3A input Channel 3 inverter input. TTL-compatible logic input.
6 3Y output Channel 3 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA.
7 GND power_in Ground reference for the device (0 V).
8 4Y output Channel 4 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA.
9 4A input Channel 4 inverter input. TTL-compatible logic input.
10 5Y output Channel 5 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA.
11 5A input Channel 5 inverter input. TTL-compatible logic input.
12 6Y output Channel 6 inverter output. Open-collector, rated to 30 V off-state, sinks up to 40 mA.
13 6A input Channel 6 inverter input. TTL-compatible logic input.
14 VCC power_in Supply voltage. Recommended operating range 4.5 V to 5.5 V (nominal 5 V), absolute maximum 7 V. Decouple with 100 nF near the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74ls06dr.step 195 KB You want the bare part, or you mark your own boards.
sn74ls06dr-etched.step 2.4 MB You want the part with SN74LS06DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 605 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 (31 pp, sha256 9a44a286a822094e, 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).
