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 internal connection. Pin is not bonded to the die and may be left floating or tied to a static level. |+| 2 | A | input | Inverter logic input A. CMOS input with Schmitt-trigger action for tolerance of slow input rise/fall times. VIH = 3.85 V min at VCC = 5.5 V; VIL = 1.65 V max at VCC = 5.5 V. Input voltage range 0 to 5.5 V independent of VCC. |+| 3 | GND | power_in | Ground reference pin (0 V). All input and output voltages are referenced to this pin. |+| 4 | Y | output | Inverter logic output Y = /A. Push-pull CMOS output rated ±8 mA drive at VCC = 5 V (±4 mA at 3.3 V, ±50 uA at 2 V). VOH ≥ 3.8 V at 8 mA / VCC = 4.5 V; VOL ≤ 0.44 V at 8 mA. |+| 5 | VCC | power_in | Positive supply voltage input. Recommended operating range 2 V to 5.5 V; absolute maximum 7 V. Quiescent ICC max 10 uA at 5.5 V. Bypass with a local 0.1 uF ceramic capacitor to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-353 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `SN74AHC1G04DCKR`+- `SN74AHC1G04DCKRDCKT`+- `SN74AHC1G04DCKRDBVR`+- `SN74AHC1G04DCKRDBVT`+- `SN74AHC1G04DCKRDRLR`++## CAD (KiCad official)++- Symbol: `SN74AHC1G04DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SOT-353 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/sn74ahc1g04.pdf) (26 pp, sha256 `880e5b3989b61227`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
