Texas Instruments · Translators, Level Shifters · TSSOP-20

TXS0108EPWR 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 (1.4V-3.6V). Auto-sensing bidirectional level-shifted channel paired with B1.
2 VCCA power_in A-port supply voltage. 1.4V ≤ VCCA ≤ 3.6V and VCCA ≤ VCCB. Sets the logic level of the A-port I/Os.
3 A2 bidirectional Input/output 2. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B2.
4 A3 bidirectional Input/output 3. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B3.
5 A4 bidirectional Input/output 4. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B4.
6 A5 bidirectional Input/output 5. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B5.
7 A6 bidirectional Input/output 6. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B6.
8 A7 bidirectional Input/output 7. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B7.
9 A8 bidirectional Input/output 8. Referenced to VCCA. Auto-sensing bidirectional level-shifted channel paired with B8.
10 OE input Tri-state output-mode enable. Pull OE low to place all A/B outputs into 3-state (Hi-Z) mode. Referenced to VCCA. Tie to GND through a pull-down during power sequencing to hold outputs in Hi-Z.
11 GND power_in Ground reference for the device.
12 B8 bidirectional Input/output 8. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A8.
13 B7 bidirectional Input/output 7. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A7.
14 B6 bidirectional Input/output 6. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A6.
15 B5 bidirectional Input/output 5. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A5.
16 B4 bidirectional Input/output 4. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A4.
17 B3 bidirectional Input/output 3. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A3.
18 B2 bidirectional Input/output 2. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A2.
19 VCCB power_in B-port supply voltage. 1.65V ≤ VCCB ≤ 5.5V and must be ≥ VCCA. Sets the logic level of the B-port I/Os.
20 B1 bidirectional Input/output 1. Referenced to VCCB. Auto-sensing bidirectional level-shifted channel paired with A1.
