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 | OE | input | Active-low output enable. When OE is low, the buffer passes A to Y; when OE is high, Y is placed in a high-impedance (3-state) condition. TTL-compatible input, VIH >= 2 V, VIL <= 0.8 V. |+| 2 | A | input | Data input to the buffer. Value is driven to Y when OE is low. TTL-compatible logic input (VIH >= 2 V, VIL <= 0.8 V). |+| 3 | GND | power_in | Ground reference (0 V) for the device. |+| 4 | Y | tri_state | 3-state buffered output. Follows the A input when OE is low; high-impedance when OE is high. Rated ±8 mA drive at VCC = 5 V. |+| 5 | VCC | power_in | Supply voltage input, 4.5 V to 5.5 V recommended operating range (absolute max 7.0 V). Quiescent supply current ICC <= 10 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | UMW |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AHCT1G125DCKRDCKR`+- `SN74AHCT1G125DCKRDBVR`+- `SN74AHCT1G125DCKRDRYR`++## CAD (KiCad official)++- Symbol: `SN74AHCT1G125DCKR`+- 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:** [UMW datasheet](docs/sn74ahct1g125dckr-datasheet.pdf) (10 pp, sha256 `72ab42624be87c31`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
