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 LOW the buffer drives Y from A; when HIGH the Y output is placed in high-impedance (3-STATE). Tolerates input voltages up to 6 V independent of VCC. |+| 2 | A | input | Buffer data input. Propagates to output Y when /OE is LOW. Over-voltage tolerant (up to 6 V) allowing 5 V-to-3 V translation. High-impedance when VCC = 0 V. |+| 3 | GND | power_in | Ground / 0 V reference for the device. |+| 4 | Y | tri_state | Three-state buffer output. Drives ±24 mA at 3 V VCC (±32 mA at 4.5 V). Placed in high-impedance when /OE is HIGH; tolerates voltages above VCC when in the 3-STATE condition. |+| 5 | VCC | power_in | Positive supply. Operating range 1.65 V to 5.5 V (data retention down to 1.5 V). Quiescent supply current ICC = 20 µA max. Bypass locally with a 0.1 µF ceramic to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | onsemi |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `NC7SZ125P5XP5X`+- `NC7SZ125P5XM5X`+- `NC7SZ125P5XL6X`+- `NC7SZ125P5XFHX`++## CAD (KiCad official)++- Symbol: `NC7SZ125P5X`+- 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:** [onsemi datasheet](https://www.onsemi.com/pdf/datasheet/nc7sz125p5x-d.pdf) (12 pp, sha256 `2c35f890b62b9580`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
