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 | A1 | bidirectional | Input/output 1. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 2 | VCCA | power_in | A-port supply voltage. 1.1V ≤ VCCA ≤ 3.6V, and VCCA ≤ VCCB. Sets the logic level for the A-side I/Os and the OE input reference. |+| 3 | A2 | bidirectional | Input/output 2. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 4 | A3 | bidirectional | Input/output 3. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 5 | A4 | bidirectional | Input/output 4. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 6 | A5 | bidirectional | Input/output 5. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 7 | A6 | bidirectional | Input/output 6. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 8 | A7 | bidirectional | Input/output 7. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 9 | A8 | bidirectional | Input/output 8. Referenced to VCCA. Bidirectional level-translated data line on the A port side. |+| 10 | OE | input | Output enable. Pull OE low to place all outputs in the high-impedance (3-state) mode. Referenced to VCCA. During power-up/down OE should be tied to GND through a pulldown resistor. |+| 11 | GND | power_in | Ground reference for the device. |+| 12 | B8 | bidirectional | Input/output 8. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 13 | B7 | bidirectional | Input/output 7. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 14 | B6 | bidirectional | Input/output 6. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 15 | B5 | bidirectional | Input/output 5. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 16 | B4 | bidirectional | Input/output 4. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 17 | B3 | bidirectional | Input/output 3. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 18 | B2 | bidirectional | Input/output 2. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |+| 19 | VCCB | power_in | B-port supply voltage. 1.65V ≤ VCCB ≤ 5.5V. Must be greater than or equal to VCCA. Sets the logic level for the B-side I/Os. |+| 20 | B1 | bidirectional | Input/output 1. Referenced to VCCB. Bidirectional level-translated data line on the B port side. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-20 |+| Category | Logic |+| Pins | 20 |++## Ordering variants++Same part, different packaging or reel option.++- `TXB0108PWR`+- `TXB0108PWRDGS`+- `TXB0108PWRDGSR`+- `TXB0108PWRDQS`+- `TXB0108PWRDQSR`+- `TXB0108PWRRGY`+- `TXB0108PWRRGYR`+- `TXB0108PWRRKS`+- `TXB0108PWRRKSR`+- `TXB0108PWRRUK`+- `TXB0108PWRRUKR`+- `TXB0108PWRYZP`+- `TXB0108PWRYZPR`+- `TXB0108PWRNME`+- `TXB0108PWRNMER`+- `TXB0108PWRZXY`+- `TXB0108PWRGXY`++## CAD (KiCad official)++- Symbol: `TXB0108PWR`+- 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:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/txb0108.pdf) (47 pp, sha256 `8f8720b78129d8b4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
