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.

3D model downloads

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.
