**DIOO** · USB Converters · MSOP-10

DIO32320MP10 from DIOO, in a MSOP-10. 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 | VCC | power_in | Supply voltage; operating range 2.7V to 5.5V, absolute maximum 6.0V. |
| 2 | SEL | input | Switch select input; logic-low connects D±→HSD1±, logic-high connects D±→HSD2± (control input voltage range 0V to VCC). |
| 3 | D+ | bidirectional | USB data bus positive common port; bi-directional, switch I/O voltage 0V to 5.5V, Ron 6Ω typ / 8Ω max at VCC=3.0V. |
| 4 | D- | bidirectional | USB data bus negative common port; bi-directional, switch I/O voltage 0V to 5.5V, Ron 6Ω typ / 8Ω max at VCC=3.0V. |
| 5 | GND | power_in | Ground reference for all signals and supply. |
| 6 | HSD1- | bidirectional | Multiplexed source port 1 negative; connected to D- when SEL=L and /OE=L, switch I/O voltage 0V to 5.5V. |
| 7 | HSD1+ | bidirectional | Multiplexed source port 1 positive; connected to D+ when SEL=L and /OE=L, switch I/O voltage 0V to 5.5V. |
| 8 | HSD2- | bidirectional | Multiplexed source port 2 negative; connected to D- when SEL=H and /OE=L, switch I/O voltage 0V to 5.5V. |
| 9 | HSD2+ | bidirectional | Multiplexed source port 2 positive; connected to D+ when SEL=H and /OE=L, switch I/O voltage 0V to 5.5V. |
| 10 | /OE | input | Active-low switch enable; high disconnects all ports (power-off/on protection), low enables the SEL-selected channel; control input range 0V to VCC. |
