**Texas Instruments** · USB Converters · HVQFN-16-EP(3x3)

TUSB1106RGTR from Texas Instruments, in a HVQFN-16-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 | OE | input | Active-LOW output enable (CMOS level with respect to VCC(I/O)) that enables the transceiver to transmit data on the USB bus. |
| 2 | RCV | output | Differential data receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven LOW when SUSPND is HIGH and stable during SE0. |
| 3 | VP | output | Single-ended D+ receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven HIGH when no supply is connected to VCC(5.0) and Vreg(3.3). |
| 4 | VM | output | Single-ended D- receiver output (CMOS level with respect to VCC(I/O), push-pull, 4-mA drive); driven HIGH when no supply is connected to VCC(5.0) and Vreg(3.3). |
| 5 | SUSPND | input | Suspend input (CMOS level with respect to VCC(I/O)); HIGH enables the low-power state while the USB bus is inactive and drives RCV LOW. |
| 6 | GND | power_in | Ground supply pin on the TUSB1106 RGT package. |
| 7 | VCC(I/O) | power_in | Digital I/O supply voltage of 1.65 to 3.6 V, independent of VCC(5.0) and Vreg(3.3) and must never exceed Vreg(3.3); D+ and D- are 3-state when it is not connected. |
| 8 | SPEED | input | Speed selection input (CMOS level with respect to VCC(I/O)) that sets the D+/D- slew rate: LOW is low speed (1.5 Mbit/s), HIGH is full speed (12 Mbit/s). |
| 9 | D- | bidirectional | Negative USB data bus connection (analog, differential); for low-speed mode connect to Vpu(3.3) via a 1.5-kOhm resistor. |
| 10 | D+ | bidirectional | Positive USB data bus connection (analog, differential); for full-speed mode connect to Vpu(3.3) via a 1.5-kOhm resistor. |
| 11 | VPO | input | Driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger) for the differential input data interface. |
| 12 | VMO | input | Driver data input (CMOS level with respect to VCC(I/O), Schmitt trigger) for the differential input data interface. |
| 13 | Vreg(3.3) | power_out | Regulated 3 V to 3.6 V output during 5-V operation, needs a decoupling capacitor of at least 0.1 uF, and is the supply input for 3.3 V ±10% operation. |
| 14 | VCC(5.0) | power_in | Internal regulator supply input of 4 V to 5.5 V, which can connect directly to USB VBUS; connect to Vreg(3.3) for the regulator bypass option. |
| 15 | Vpu(3.3) | power_out | Pullup supply voltage (3.3 V ±10%) for the external 1.5-kOhm resistor on D+ or D-; high impedance when SOFTCON is LOW, connected internally to Vreg(3.3) when SOFTCON is HIGH. |
| 16 | SOFTCON | input | Software-controlled USB connection input; HIGH applies 3.3 V to Vpu(3.3) for the external 1.5-kOhm pullup, allowing software connect/disconnect signaling. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
