txs0102dcur.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

TXS0102DCUR

Texas Instruments · Translators / Level Shifters · VSSOP-8

TXS0102DCUR from Texas Instruments, in a VSSOP-8. 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 B2 bidirectional Input/output B, channel 2. Referenced to VCCB (2.3 V to 5.5 V). Bidirectional level-shifted I/O; requires OE high to be active.
2 GND power_in Ground reference for the device. Common return for both VCCA and VCCB supplies.
3 VCCA power_in A-port supply voltage. 1.65 V <= VCCA <= 3.6 V, and VCCA must be <= VCCB. Sets the logic level for the A-side I/Os (A1, A2).
4 A2 bidirectional Input/output A, channel 2. Referenced to VCCA (1.65 V to 3.6 V). Bidirectional level-shifted I/O paired with B2.
5 A1 bidirectional Input/output A, channel 1. Referenced to VCCA (1.65 V to 3.6 V). Bidirectional level-shifted I/O paired with B1.
6 OE input Output enable, active high. Referenced to VCCA. Pull OE low to place all outputs in the high-impedance (3-state) mode; drive high for normal translation. Tie to GND through a pulldown during power-up/down to guarantee Hi-Z.
7 VCCB power_in B-port supply voltage. 2.3 V <= VCCB <= 5.5 V, and must be >= VCCA. Sets the logic level for the B-side I/Os (B1, B2).
8 B1 bidirectional Input/output B, channel 1. Referenced to VCCB (2.3 V to 5.5 V). Bidirectional level-shifted I/O; requires OE high to be active.

CAD (KiCad official)

  • Symbol: TXS0102DCUR
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: txs0102dcur-etched.step / txs0102dcur-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); txs0102dcur.step / txs0102dcur.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
txs0102dcur.step 122 KB You want the bare part, or you mark your own boards.
txs0102dcur-etched.step 2.4 MB You want the part with TXS0102DCUR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 584 faces against 147 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.
