# TXS0101DBVR

**Texas Instruments** · Translators / Level Shifters · SOT-23-6

TXS0101DBVR from Texas Instruments, in a SOT-23-6. 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. 1.65V <= VCCA <= 3.6V and VCCA <= VCCB. Sets the logic reference for the A-side I/O. |
| 2 | GND | power_in | Device ground reference for both A and B supply rails. |
| 3 | A | bidirectional | Input/output A. Referenced to VCCA. Auto-direction-sensing level-shifted data pin for the A-side (low-voltage side). |
| 4 | B | bidirectional | Input/output B. Referenced to VCCB. Auto-direction-sensing level-shifted data pin for the B-side (high-voltage side). |
| 5 | OE | input | Output enable. Pull OE low to place all outputs in 3-state (high-Z) mode. Referenced to VCCA. Tie to GND through a pull-down resistor during power-up/down to hold outputs in Hi-Z. |
| 6 | VCCB | power_in | B-port supply voltage. 2.3V <= VCCB <= 5.5V. Sets the logic reference for the B-side I/O and must be >= VCCA. |

## Ordering variants

Same part, different packaging or reel option.

## CAD (KiCad official)

- Symbol: `TXS0101DBVR`
- Footprint: `Package_TO_SOT_SMD:SOT-23-6`
- 3D model: SOT-23-6 (KiCad packages3D, STEP)
- 3D model files: `txs0101dbvr-etched.step` / `txs0101dbvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `txs0101dbvr.step` / `txs0101dbvr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`txs0101dbvr.step`](txs0101dbvr.step) | 97 KB | You want the bare part, or you mark your own boards. |
| [`txs0101dbvr-etched.step`](txs0101dbvr-etched.step) | 2.0 MB | You want the part with `TXS0101DBVR` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 504 faces against 117 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.
