TXS0104EPWR

Texas Instruments · Translators / Level Shifters · TSSOP-14

TXS0104EPWR from Texas Instruments, in a TSSOP-14. 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.

CAD (KiCad official)

  • Symbol: TXS0104EPWR
  • Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
  • 3D model: TSSOP-14 (KiCad packages3D, STEP)
  • 3D model files: txs0104epwr-etched.step / txs0104epwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); txs0104epwr.step / txs0104epwr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
txs0104epwr.step 194 KB You want the bare part, or you mark your own boards.
txs0104epwr-etched.step 2.4 MB You want the part with TXS0104EPWR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 623 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
