Texas Instruments · Inverters · TSSOP-14

SN74HCT14PWR from Texas Instruments, in a TSSOP-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 Schmitt-trigger inverter input. TTL-voltage-compatible; VT+ ≈ 1.7 V, VT- ≈ 1.0 V at VCC = 5 V (hysteresis ≈ 0.65 V). Input current ±1 µA max.
2 1Y output Channel 1 inverter output (Y = /A). Push-pull CMOS output rated ±4 mA at VCC = 5 V; drives up to 10 LSTTL loads.
3 2A input Channel 2 Schmitt-trigger inverter input. Same thresholds as 1A.
4 2Y output Channel 2 inverter output (Y = /A). ±4 mA drive at VCC = 5 V.
5 3A input Channel 3 Schmitt-trigger inverter input.
6 3Y output Channel 3 inverter output (Y = /A). ±4 mA drive at VCC = 5 V.
7 GND power_in Ground reference (0 V) for the device.
8 4Y output Channel 4 inverter output (Y = /A). ±4 mA drive at VCC = 5 V.
9 4A input Channel 4 Schmitt-trigger inverter input.
10 5Y output Channel 5 inverter output (Y = /A). ±4 mA drive at VCC = 5 V.
11 5A input Channel 5 Schmitt-trigger inverter input.
12 6Y output Channel 6 inverter output (Y = /A). ±4 mA drive at VCC = 5 V.
13 6A input Channel 6 Schmitt-trigger inverter input.
14 VCC power_in Positive supply, 4.5 V to 5.5 V recommended (7 V absolute max). Typical ICC = 20 µA max at 25 °C.

Two STEP files. Same geometry, different body top:

File Size Use it when
sn74hct14pwr.step 194 KB You want the bare part, or you mark your own boards.
sn74hct14pwr-etched.step 2.3 MB You want the part with SN74HCT14PWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 597 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 (34 pp, sha256 1c4cf5c87d8c8a22, 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).
