# SN74AHC1G14DBVR

**Texas Instruments** · Inverters · SOT-23-5

SN74AHC1G14DBVR from Texas Instruments, in a SOT-23-5. 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 | NC | unconnected | No connect. Not internally bonded; may be left floating or tied to GND. |
| 2 | A | input | Schmitt-trigger data input. Input threshold VT+ ≈ 3.15 V max and VT- ≈ 1.35 V min at VCC = 4.5 V, providing typical hysteresis of 0.4-0.5 V. Input voltage range 0 to 5.5 V; input leakage ±1 µA max. |
| 3 | GND | power_in | Ground reference (0 V) for the device. |
| 4 | Y | output | Inverted CMOS data output (Y = /A). Push-pull totem-pole output rated ±8 mA drive at VCC = 5 V (±4 mA at 3.3 V). VOH ≥ 3.7 V at IOH = -8 mA (VCC = 4.5 V); VOL ≤ 0.55 V at IOL = 8 mA. |
| 5 | VCC | power_in | Supply voltage input. Recommended operating range 2 V to 5.5 V (absolute max 7 V). Typical ICC = 1 µA, 10 µA max. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin. |

## CAD (KiCad official)

- Symbol: `SN74AHC1G14DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `sn74ahc1g14dbvr-etched.step` / `sn74ahc1g14dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sn74ahc1g14dbvr.step` / `sn74ahc1g14dbvr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`sn74ahc1g14dbvr.step`](sn74ahc1g14dbvr.step) | 85 KB | You want the bare part, or you mark your own boards. |
| [`sn74ahc1g14dbvr-etched.step`](sn74ahc1g14dbvr-etched.step) | 2.1 MB | You want the part with `SN74AHC1G14DBVR` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 556 faces against 102 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.
