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 | Output enable input for buffer 1 (active LOW). LOW enables 1Y to follow 1A; HIGH puts 1Y in high-impedance OFF-state. TTL input levels (VIH min 2.0 V, VIL max 0.8 V at VCC = 4.5-5.5 V). |+| 2 | 1A | input | Data input for buffer 1. Passed through to 1Y when 1OE is LOW. TTL input levels; input leakage ±0.1 µA typ, input capacitance 3.5 pF typ. |+| 3 | 1Y | tri_state | Data output for buffer 1. Drives the value of 1A when 1OE is LOW; high-impedance when 1OE is HIGH. Rated for IO up to ±35 mA absolute max; VOH ≥ 3.98 V at IO = -6 mA, VOL ≤ 0.26 V at IO = 6 mA (VCC = 4.5 V). |+| 4 | 2OE | input | Output enable input for buffer 2 (active LOW). LOW enables 2Y to follow 2A; HIGH puts 2Y in high-impedance OFF-state. |+| 5 | 2A | input | Data input for buffer 2. Passed through to 2Y when 2OE is LOW. |+| 6 | 2Y | tri_state | Data output for buffer 2. Drives the value of 2A when 2OE is LOW; high-impedance when 2OE is HIGH. |+| 7 | GND | power_in | Ground reference (0 V). Maximum sustained ground current ±70 mA per absolute maximum ratings. |+| 8 | 3Y | tri_state | Data output for buffer 3. Drives the value of 3A when 3OE is LOW; high-impedance when 3OE is HIGH. |+| 9 | 3A | input | Data input for buffer 3. Passed through to 3Y when 3OE is LOW. |+| 10 | 3OE | input | Output enable input for buffer 3 (active LOW). LOW enables 3Y to follow 3A; HIGH puts 3Y in high-impedance OFF-state. |+| 11 | 4Y | tri_state | Data output for buffer 4. Drives the value of 4A when 4OE is LOW; high-impedance when 4OE is HIGH. |+| 12 | 4A | input | Data input for buffer 4. Passed through to 4Y when 4OE is LOW. |+| 13 | 4OE | input | Output enable input for buffer 4 (active LOW). LOW enables 4Y to follow 4A; HIGH puts 4Y in high-impedance OFF-state. |+| 14 | VCC | power_in | Positive supply voltage. Recommended 4.5 V to 5.5 V for 74HCT125; absolute maximum -0.5 V to +7 V. Supply current ICC ≤ 8 µA at 25 °C (VCC = 5.5 V). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | SOIC-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++Same part, different packaging or reel option.++- `74HCT125DD`+- `74HCT125DPW`++## CAD (KiCad official)++- Symbol: `74HCT125D`+- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`+- 3D model: SOIC-14 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8579712006357565440) (13 pp, sha256 `3b5da3a3dcae2624`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
