TS3USB221ARSERG4 from Texas Instruments, in a 10-UFQFN. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model). The symbol is generated from that pin table and the footprint is an Adom_Gen land derived from the manufacturer drawing; the 3D model is generated to fit it.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1D+ | bidirectional | USB port 1 positive differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 2 | 1D- | bidirectional | USB port 1 negative differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 3 | 2D+ | bidirectional | USB port 2 positive differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 4 | 2D- | bidirectional | USB port 2 negative differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | OE | input | Bus-switch enable input; the device enters a low-power mode of 1 µA when OE is disabled, and its high-level input is 0.46 × VCC minimum with low-level input 0.25 × VCC maximum. |
| 7 | D- | bidirectional | Common USB port negative differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 8 | D+ | bidirectional | Common USB port positive differential I/O, with I/O voltage limited to 0 V to 5.5 V under recommended operating conditions. |
| 9 | S | input | Select input that chooses between USB port 1 and USB port 2; for VCC of 2.7 V to 3.6 V the high-level input is 0.46 × VCC minimum and the low-level input is 0.25 × VCC maximum. |
| 10 | VCC | power_in | Supply voltage, recommended operating range 2.3 V to 3.6 V with absolute maximum rating of 4.6 V. |
