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 | DIR | input | Direction control input. LOW routes Bn to An (B->A); HIGH routes An to Bn (A->B). CMOS/TTL-compatible Schmitt-trigger input. |+| 2 | A0 | bidirectional | A-side bus data input/output bit 0. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 3 | A1 | bidirectional | A-side bus data input/output bit 1. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 4 | A2 | bidirectional | A-side bus data input/output bit 2. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 5 | A3 | bidirectional | A-side bus data input/output bit 3. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 6 | A4 | bidirectional | A-side bus data input/output bit 4. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 7 | A5 | bidirectional | A-side bus data input/output bit 5. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 8 | A6 | bidirectional | A-side bus data input/output bit 6. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 9 | A7 | bidirectional | A-side bus data input/output bit 7. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 10 | GND | power_in | Ground reference (0 V). Connect to system ground. |+| 11 | B7 | bidirectional | B-side bus data input/output bit 7. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 12 | B6 | bidirectional | B-side bus data input/output bit 6. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 13 | B5 | bidirectional | B-side bus data input/output bit 5. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 14 | B4 | bidirectional | B-side bus data input/output bit 4. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 15 | B3 | bidirectional | B-side bus data input/output bit 3. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 16 | B2 | bidirectional | B-side bus data input/output bit 2. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 17 | B1 | bidirectional | B-side bus data input/output bit 1. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 18 | B0 | bidirectional | B-side bus data input/output bit 0. Direction set by DIR; enters high-impedance when OE is HIGH. |+| 19 | OE | input | Output enable, active LOW. LOW enables the transceiver drivers; HIGH forces both An and Bn buses to the high-impedance OFF-state. |+| 20 | VCC | power_in | Supply voltage input. Recommended operating range 1.65 V to 3.6 V (functional from 1.2 V); absolute maximum 6.5 V. Decouple locally with 100 nF to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Nexperia |+| Package | TSSOP-20 |+| Category | Logic |+| Pins | 20 |++## Ordering variants++- `74LVC245APWAPW`+- `74LVC245APWPW`+- `74LVC245APWAD`+- `74LVC245APWD`+- `74LVC245APWABQ`+- `74LVC245APWABZ`++## CAD (KiCad official)++- Symbol: `74LVC245APW`+- Footprint: `Package_SO:TSSOP-20_4.4x6.5mm_P0.65mm`+- 3D model: TSSOP-20 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Nexperia datasheet](https://assets.nexperia.com/documents/data-sheet/74LVC245APW.pdf) (16 pp, sha256 `e87a15c19e7cc6c5`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
