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 | VCCA | power_in | A-port supply voltage. 1.65 V <= VCCA <= 3.6 V and VCCA <= VCCB. Also biases the OE input threshold. Decouple with a 0.1 uF cap close to the pin. |+| 2 | A1 | bidirectional | Input/output A1. Referenced to VCCA. Bidirectional level-translated I/O paired with B1. |+| 3 | A2 | bidirectional | Input/output A2. Referenced to VCCA. Bidirectional level-translated I/O paired with B2. |+| 4 | A3 | bidirectional | Input/output A3. Referenced to VCCA. Bidirectional level-translated I/O paired with B3. |+| 5 | A4 | bidirectional | Input/output A4. Referenced to VCCA. Bidirectional level-translated I/O paired with B4. |+| 6 | NC | unconnected | No internal connection. Leave floating or tie to ground. |+| 7 | GND | power_in | Device ground reference for both supply rails. |+| 8 | OE | input | 3-state output-mode enable, referenced to VCCA. Drive OE low to place all A- and B-port outputs in Hi-Z. For Hi-Z during power up/down, tie OE to GND through a pull-down resistor (value set by the driver's current-sourcing capability). |+| 9 | NC | unconnected | No internal connection. Leave floating or tie to ground. |+| 10 | B4 | bidirectional | Input/output B4. Referenced to VCCB. Bidirectional level-translated I/O paired with A4. |+| 11 | B3 | bidirectional | Input/output B3. Referenced to VCCB. Bidirectional level-translated I/O paired with A3. |+| 12 | B2 | bidirectional | Input/output B2. Referenced to VCCB. Bidirectional level-translated I/O paired with A2. |+| 13 | B1 | bidirectional | Input/output B1. Referenced to VCCB. Bidirectional level-translated I/O paired with B1. |+| 14 | VCCB | power_in | B-port supply voltage. 2.3 V <= VCCB <= 5.5 V and VCCB >= VCCA. Decouple with a 0.1 uF cap close to the pin. Either supply (VCCA or VCCB) may be ramped first - no sequencing required. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | TSSOP-14 |+| Category | Logic |+| Pins | 14 |++## Ordering variants++- `TXS0104EPWRPW`+- `TXS0104EPWRPWR`+- `TXS0104EPWRD`+- `TXS0104EPWRRGY`+- `TXS0104EPWRBQA`+- `TXS0104EPWRZXU`+- `TXS0104EPWRNMN`+- `TXS0104EPWRYZT`+- `TXS0104EPWRRUT`++## CAD (KiCad official)++- Symbol: `TXS0104EPWR`+- 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/txs0104e.pdf) (51 pp, sha256 `8622dc5ff42a36e2`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
