TS3DS10224RUKR from Texas Instruments, in a WQFN-20-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INA+ | bidirectional | A channel positive differential signal path |
| 2 | INA- | bidirectional | A channel negative differential signal path |
| 3 | INB+ | bidirectional | B channel positive differential signal path |
| 4 | INB- | bidirectional | B channel negative differential signal path |
| 5 | GND | power_in | Ground |
| 6 | OUTB1+ | bidirectional | B channel output 1 positive differential signal path |
| 7 | OUTB1- | bidirectional | B channel output 1 negative differential signal path |
| 8 | OUTB0+ | bidirectional | B channel output 0 positive differential signal path |
| 9 | OUTB0- | bidirectional | B channel output 0 negative differential signal path |
| 10 | ENB | input | Enable B channel; LOW disables channel B and places signal path in high impedance state, HIGH enables channel B |
| 11 | SBO | input | Select B channel output; LOW selects OUTB0 signals, HIGH selects OUTB1 signals |
| 12 | SBI | input | Select B channel input; LOW selects INA signals to pass through B channel, HIGH selects INB signals |
| 13 | VCC | power_in | Power supply with recommended operating voltage range 3V to 3.6V |
| 14 | SAI | input | Select A channel input; LOW selects INB signals to pass through A channel, HIGH selects INA signals |
| 15 | SAO | input | Select A channel output; LOW selects OUTA0 signals, HIGH selects OUTA1 signals |
| 16 | ENA | input | Enable A channel; LOW disables channel A and places signal path in high impedance state, HIGH enables channel A |
| 17 | OUTA0- | bidirectional | A channel output 0 negative differential signal path |
| 18 | OUTA0+ | bidirectional | A channel output 0 positive differential signal path |
| 19 | OUTA1- | bidirectional | A channel output 1 negative differential signal path |
| 20 | OUTA1+ | bidirectional | A channel output 1 positive differential signal path |
| 21 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
