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 | Output Enable. Active-HIGH 3-state control: when HIGH, the buffer drives Y from A; when LOW, Y enters high-impedance (Z). TTL-compatible input (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5-5.5 V). |+| 2 | A | input | Data input to the non-inverting buffer. TTL-compatible logic input (VIH = 2.0 V min, VIL = 0.8 V max) with Schmitt-trigger action for slower input transitions. |+| 3 | GND | power_in | Ground reference (0 V). Continuous current through GND rated at -50 mA maximum. |+| 4 | Y | tri_state | Data output. Non-inverting 3-state buffer output driving ±8 mA at VCC = 5.0 V. Enters high-impedance (Z) when OE is LOW. |+| 5 | VCC | power_in | Supply voltage input. Recommended operating range 4.5 V to 5.5 V (absolute max -0.5 V to 6.5 V). Continuous current through VCC rated at 50 mA maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Diodes Incorporated |+| Package | SOT-25 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++Same part, different packaging or reel option.++- `74AHCT1G126W5-7`+- `74AHCT1G126W5-7SE-7`++## CAD (KiCad official)++- Symbol: `74AHCT1G126W5-7`+- Footprint: `Package_TO_SOT_SMD:SOT-23-5`+- 3D model: SOT-25 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Diodes Incorporated datasheet](docs/74ahct1g126w5-7-datasheet.pdf) (9 pp, sha256 `ff02d445a69466d5`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
