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-high output enable. When OE = high, the buffer passes A to Y; when OE = low, Y is placed in a high-impedance (Hi-Z) state. CMOS input, V_IH ≥ 3.85 V at V_CC = 5.5 V. |+| 2 | A | input | Data input to the buffer. Logic level at A is driven to Y output when OE is high. CMOS input; unused inputs must be tied to V_CC or GND per TI floating-input guidance. |+| 3 | GND | power_in | Ground reference (0 V) for the device. |+| 4 | Y | tri_state | 3-state buffer output. Drives the logic level of A when OE is high; enters high-impedance when OE is low. Rated ±8 mA drive at V_CC = 5 V (±4 mA at 3.3 V). |+| 5 | VCC | power_in | Positive supply voltage, 2 V to 5.5 V recommended operating range. Absolute maximum 7 V. Typical I_CC ≤ 10 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AHC1G126DCKR`+- `SN74AHC1G126DCKRDCKT`+- `SN74AHC1G126DCKRDBVR`+- `SN74AHC1G126DCKRDBVT`+- `SN74AHC1G126DCKRDRLR`++## CAD (KiCad official)++- Symbol: `SN74AHC1G126DCKR`+- 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/sn74ahc1g126.pdf) (27 pp, sha256 `6824188e88dcff51`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
