**Nexperia** · Inverters · TSSOP-14

74HC14PW from Nexperia, 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 | Schmitt-trigger data input to inverter channel 1. Input voltage range 0 V to VCC (VCC = 2.0 V to 6.0 V). Input clamp diodes permit series-resistor interfacing above VCC. |
| 2 | 1Y | output | Inverted CMOS output of Schmitt-trigger channel 1. Push-pull drive; typ. IO = ±5.2 mA at VCC = 6.0 V. |
| 3 | 2A | input | Schmitt-trigger data input to inverter channel 2. Input voltage range 0 V to VCC. |
| 4 | 2Y | output | Inverted CMOS output of Schmitt-trigger channel 2. Push-pull drive. |
| 5 | 3A | input | Schmitt-trigger data input to inverter channel 3. Input voltage range 0 V to VCC. |
| 6 | 3Y | output | Inverted CMOS output of Schmitt-trigger channel 3. Push-pull drive. |
| 7 | GND | power_in | Ground reference (0 V). |
| 8 | 4Y | output | Inverted CMOS output of Schmitt-trigger channel 4. Push-pull drive. |
| 9 | 4A | input | Schmitt-trigger data input to inverter channel 4. Input voltage range 0 V to VCC. |
| 10 | 5Y | output | Inverted CMOS output of Schmitt-trigger channel 5. Push-pull drive. |
| 11 | 5A | input | Schmitt-trigger data input to inverter channel 5. Input voltage range 0 V to VCC. |
| 12 | 6Y | output | Inverted CMOS output of Schmitt-trigger channel 6. Push-pull drive. |
| 13 | 6A | input | Schmitt-trigger data input to inverter channel 6. Input voltage range 0 V to VCC. |
| 14 | VCC | power_in | Positive supply voltage. Recommended VCC = 2.0 V to 6.0 V (74HC14). Absolute maximum -0.5 V to +7 V. |

## Ordering variants

- `74HC14PW`
- `74HC14PWD`
- `74HC14PWBQ`

## CAD (KiCad official)

- Symbol: `74HC14PW`
- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`
- 3D model: TSSOP-14 (KiCad packages3D, STEP)
- 3D model files: `74hc14pw-etched.step` / `74hc14pw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `74hc14pw.step` / `74hc14pw.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`74hc14pw.step`](74hc14pw.step) | 194 KB | You want the bare part, or you mark your own boards. |
| [`74hc14pw-etched.step`](74hc14pw-etched.step) | 1.7 MB | You want the part with `74HC14PW` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 446 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.
