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 | 1OE | input | Channel 1 output enable, active low. When low, buffer 1 output (1Y) follows input 1A; when high, 1Y is high-impedance (three-state). |+| 2 | 1A | input | Channel 1 buffer input. Logic level presented at 1Y when 1OE is low. |+| 3 | 1Y | tri_state | Channel 1 buffer output, three-state. Drives the logic level of 1A when 1OE is low; high-Z when 1OE is high. Can source/sink up to ±7.8 mA at VCC = 6 V. |+| 4 | 2OE | input | Channel 2 output enable, active low. When low, buffer 2 output (2Y) follows input 2A; when high, 2Y is high-impedance. |+| 5 | 2A | input | Channel 2 buffer input. |+| 6 | 2Y | tri_state | Channel 2 buffer output, three-state. |+| 7 | GND | power_in | Ground / negative supply return. 0 V reference. |+| 8 | 3Y | tri_state | Channel 3 buffer output, three-state. |+| 9 | 3A | input | Channel 3 buffer input. |+| 10 | 3OE | input | Channel 3 output enable, active low. |+| 11 | 4Y | tri_state | Channel 4 buffer output, three-state. |+| 12 | 4A | input | Channel 4 buffer input. |+| 13 | 4OE | input | Channel 4 output enable, active low. |+| 14 | VCC | power_in | Positive supply. Recommended 2 V to 6 V (absolute max 7 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++- `SN74HC125PWRPW`+- `SN74HC125PWRPWR`+- `SN74HC125PWRD`+- `SN74HC125PWRDR`+- `SN74HC125PWRDB`+- `SN74HC125PWRDBR`+- `SN74HC125PWRN`+- `SN74HC125PWRNS`+- `SN74HC125PWRNSR`+- `SN74HC125PWRJ`+- `SN74HC125PWRFK`++## CAD (KiCad official)++- Symbol: `SN74HC125PWR`+- Footprint: `Package_SO:TSSOP-14_4.4x5mm_P0.65mm`+- 3D model: TSSOP-14 (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/sn74hc125.pdf) (37 pp, sha256 `c21649cccf953ad9`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
