TXB0108PWR from Texas Instruments, in a TSSOP-20. 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 A1 bidirectional Input/output 1. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
2 VCCA power_in A-port supply voltage. 1.1V ≤ VCCA ≤ 3.6V, and VCCA ≤ VCCB. Sets the logic level for the A-side I/Os and the OE input reference.
3 A2 bidirectional Input/output 2. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
4 A3 bidirectional Input/output 3. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
5 A4 bidirectional Input/output 4. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
6 A5 bidirectional Input/output 5. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
7 A6 bidirectional Input/output 6. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
8 A7 bidirectional Input/output 7. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
9 A8 bidirectional Input/output 8. Referenced to VCCA. Bidirectional level-translated data line on the A port side.
10 OE input Output enable. Pull OE low to place all outputs in the high-impedance (3-state) mode. Referenced to VCCA. During power-up/down OE should be tied to GND through a pulldown resistor.
11 GND power_in Ground reference for the device.
12 B8 bidirectional Input/output 8. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
13 B7 bidirectional Input/output 7. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
14 B6 bidirectional Input/output 6. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
15 B5 bidirectional Input/output 5. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
16 B4 bidirectional Input/output 4. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
17 B3 bidirectional Input/output 3. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
18 B2 bidirectional Input/output 2. Referenced to VCCB. Bidirectional level-translated data line on the B port side.
19 VCCB power_in B-port supply voltage. 1.65V ≤ VCCB ≤ 5.5V. Must be greater than or equal to VCCA. Sets the logic level for the B-side I/Os.
20 B1 bidirectional Input/output 1. Referenced to VCCB. Bidirectional level-translated data line on the B port side.

  • 3D model: TSSOP-20 (KiCad packages3D, STEP)
  • 3D model files: txb0108pwr-etched.step / txb0108pwr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); txb0108pwr.step / txb0108pwr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (47 pp, sha256 8f8720b78129d8b4, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
