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; not electrically bonded inside the SC70-5 (DCK) package. |+| 2 | A | input | Schmitt-trigger logic input. Positive-going threshold VT+ = 1.48-1.92 V at VCC = 3 V and negative-going threshold VT− = 0.89-1.2 V (hysteresis ~0.51-0.83 V). Input voltage range 0 to 5.5 V (5-V tolerant regardless of VCC). Do not leave floating in operation. |+| 3 | GND | power_in | Device ground / 0 V reference. Connect to system ground with a low-inductance path; decouple VCC to GND with a 0.1 µF ceramic close to the pin. |+| 4 | Y | output | CMOS push-pull buffer output, Y = A. Drive strength ±24 mA at VCC = 3 V (IOH/IOL, VOH ≥ 2.4 V / VOL ≤ 0.4 V). Propagation delay tpd ≈ 1.5 ns typical (max 4.6 ns) at 3.3 V with CL = 15 pF. |+| 5 | VCC | power_in | Positive supply, 1.65 V to 5.5 V operating (1.5 V data retention only). Absolute max 6.5 V. Decouple to GND with 0.1 µF at the pin; ICC ≤ 10 µA static. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74LVC1G17DCKRDCKR`+- `SN74LVC1G17DCKRDCKT`+- `SN74LVC1G17DCKRDBVR`+- `SN74LVC1G17DCKRDBVT`+- `SN74LVC1G17DCKRDRLR`+- `SN74LVC1G17DCKRDPWR`+- `SN74LVC1G17DCKRDRYR`+- `SN74LVC1G17DCKRDSFR`+- `SN74LVC1G17DCKRYZPR`+- `SN74LVC1G17DCKRYZVR`++## CAD (KiCad official)++- Symbol: `SN74LVC1G17DCKR`+- 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/sn74lvc1g17.pdf) (53 pp, sha256 `2570a9354a9b24e7`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
