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. Leave floating or tie to a static level; the pin has no electrical function inside the device. |+| 2 | A | input | Logic input A to the inverter. TTL-voltage compatible: VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Output Y is the logical inversion of this input. |+| 3 | GND | power_in | Device ground reference (0 V). All input/output voltages are referenced to this pin. |+| 4 | Y | output | Inverter output Y = /A. Push-pull CMOS output rated ±8 mA drive at VCC = 5 V (IOH = -8 mA, IOL = 8 mA); VOH ≥ 3.94 V typ and VOL ≤ 0.36 V typ at 4.5 V. |+| 5 | VCC | power_in | Positive supply pin. Recommended operating range 4.5 V to 5.5 V (absolute max 7 V). Decouple to GND with a 0.1 µF ceramic capacitor close to the device. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AHCT1G04DCKRDCKR`+- `SN74AHCT1G04DCKRDCKT`+- `SN74AHCT1G04DCKRDBVR`+- `SN74AHCT1G04DCKRDBVT`++## CAD (KiCad official)++- Symbol: `SN74AHCT1G04DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-353_SC-70-5`+- 3D model: SC-70-5 (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/sn74ahct1g04.pdf) (24 pp, sha256 `05199cf2c623cc8b`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
