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 goes to high-impedance (3-state). Should be tied to VCC through a pullup during power up/down to ensure Hi-Z. |+| 2 | A | input | Buffer data input. CMOS input accepts voltages up to 5.5 V regardless of VCC, allowing down-voltage translation. VIH/VIL scale with VCC (e.g. 3.85 V / 1.65 V at VCC = 5.5 V). |+| 3 | GND | power_in | Device ground reference (0 V). |+| 4 | Y | tri_state | 3-state buffer output. Drives ±8 mA at VCC = 5 V (±4 mA at 3.3 V). Follows A when OE is low; high-impedance when OE is high. Should not be pulled above VCC. |+| 5 | VCC | power_in | Positive supply voltage. Recommended operating range 2 V to 5.5 V (absolute max 7 V). Typical ICC ≤ 10 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOT-23-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AHC1G125DBVRDBVR`+- `SN74AHC1G125DBVRDBVT`+- `SN74AHC1G125DBVRDCKR`+- `SN74AHC1G125DBVRDCKT`+- `SN74AHC1G125DBVRDRLR`++## CAD (KiCad official)++- Symbol: `SN74AHC1G125DBVR`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-23-5 (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/sn74ahc1g125.pdf) (27 pp, sha256 `052d22c81db989f4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
