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 | VCC | power_in | Power supply for the device, which operates from 2.4 V to 5.5 V (5.0 V nominal) and requires external decoupling capacitors close to this pin. |+| 2 | MIC_GND1/Ln1 | bidirectional | Analog audio MIC/AGND signal connection to the audio codec, which can also be used as a general-purpose I/O. |+| 3 | MIC_GND2/Ln2 | bidirectional | Analog audio MIC/AGND signal connection to the audio codec, which can also be used as a general-purpose I/O. |+| 4 | OEn | input | Active-low output enable: L selects normal operation, while H enters standby with I2C registers reset (default); it has an internal weak pull-up. |+| 5 | SEL1/SCL | input | In pin-configuration mode (I2C_EN = L) it is SEL1 for switch selection; in I2C mode it is SCL, which needs a pull-up to VI2C through 0.62 kΩ to 2.2 kΩ; failsafe input with internal weak pull-down. |+| 6 | SEL0/SDA | bidirectional | In pin-configuration mode (I2C_EN = L) it is SEL0 for switch selection; in I2C mode it is SDA, which needs a pull-up to VI2C through 0.62 kΩ to 2.2 kΩ; failsafe I/O with internal weak pull-down. |+| 7 | LnBp | bidirectional | Single-ended I/O or positive-polarity differential partner to LnBn for generic signals such as DisplayPort AUX, PCIe clock, I2C, UART, and debug. |+| 8 | LnBn | bidirectional | Single-ended I/O or negative-polarity differential partner to LnBp for generic signals such as DisplayPort AUX, PCIe clock, I2C, UART, and debug. |+| 9 | GND | power_in | Primary ground connection that must be connected to system ground. |+| 10 | SBU2 | bidirectional | Must be DC coupled to the Type-C receptacle SBU2 pin; failsafe I/O with an internal nominal 1.6 MΩ pull-down. |+| 11 | SBU1 | bidirectional | Must be DC coupled to the Type-C receptacle SBU1 pin; failsafe I/O with an internal nominal 1.6 MΩ pull-down. |+| 12 | I2C_EN | input | 3-level input that selects pin-configuration mode (L, tied to GND or floating), I2C mode with ADDR0 (M, tied to VCC/2), or I2C mode with ADDR1 (H, tied to VCC); it has an internal weak pull-down. |+| 13 | LnCn | bidirectional | Single-ended I/O or negative-polarity differential partner to LnCp for generic signals such as DisplayPort AUX, PCIe clock, I2C, UART, and debug. |+| 14 | LnCp | bidirectional | Single-ended I/O or positive-polarity differential partner to LnCn for generic signals such as DisplayPort AUX, PCIe clock, I2C, UART, and debug. |+| 15 | LnAn | bidirectional | Single-ended I/O or negative-polarity differential partner to LnAp; preferred for DisplayPort AUX and also usable for PCIe clock, I2C, UART, and debug. |+| 16 | LnAp | bidirectional | Single-ended I/O or positive-polarity differential partner to LnAn; preferred for DisplayPort AUX and also usable for PCIe clock, I2C, UART, and debug. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | UQFN-16(1.8x2.6) |+| Category | Communication Interface Chip/UART/485/232 |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `TS3USBCA420RSVR`+- Footprint: `Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm`+- 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height).
