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 low. When OE is low, the buffer drives Y from A; when high, Y is placed in the high-impedance (3-state) state. Must be tied to VCC through a pullup during power-up/down to ensure Hi-Z. |+| 2 | A | input | Data input to the buffer. CMOS-level input with hysteresis; 3.6-V tolerant regardless of VCC. |+| 3 | GND | power_in | Device ground reference. Connect to system ground. |+| 4 | Y | tri_state | Buffered 3-state output. Drives A when OE is low; high-impedance when OE is high. Balanced CMOS push-pull output. |+| 5 | VCC | power_in | Positive supply, 0.8 V to 3.6 V recommended operating range (absolute maximum 4.6 V). Bypass locally with a ceramic capacitor. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-5 |+| Category | Logic |+| Pins | 5 |++## Ordering variants++- `SN74AUP1G125DCKRDCK`+- `SN74AUP1G125DCKRDCKR`+- `SN74AUP1G125DCKRDCKT`+- `SN74AUP1G125DCKRDBV`+- `SN74AUP1G125DCKRDBVR`+- `SN74AUP1G125DCKRDBVT`+- `SN74AUP1G125DCKRDRL`+- `SN74AUP1G125DCKRDRLR`+- `SN74AUP1G125DCKRDPW`+- `SN74AUP1G125DCKRDPWR`+- `SN74AUP1G125DCKRDRY`+- `SN74AUP1G125DCKRDRYR`+- `SN74AUP1G125DCKRDSF`+- `SN74AUP1G125DCKRDSFR`+- `SN74AUP1G125DCKRYZP`+- `SN74AUP1G125DCKRYZPR`+- `SN74AUP1G125DCKRYZT`+- `SN74AUP1G125DCKRYZTR`+- `SN74AUP1G125DCKRYFP`+- `SN74AUP1G125DCKRYFPR`++## CAD (KiCad official)++- Symbol: `SN74AUP1G125DCKR`+- 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/sn74aup1g125.pdf) (56 pp, sha256 `36ff026872794b84`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
