SGM7227YMS10G from SGMICRO, 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	Power Supply input. Operating range 1.8V to 4.3V; absolute max 4.6V referenced to GND. Bypass with 0.1µF to GND close to the pin.
2	S	input	Select input. Digital CMOS input (VIH ≥ 1.6V, VIL ≤ 0.5V). Selects which HSD source pair (HSDx+ or HSDx-) is routed to the D+/D- common bus. See Function Table.
3	D+	bidirectional	USB 2.0 high-speed data bus common (positive). Bidirectional analog switch common connected via internal switch to HSD1+ or HSD2+ depending on S/OE. Rail-to-rail I/O and tolerates VBUS short when USB device is off/on.
4	D-	bidirectional	USB 2.0 high-speed data bus common (negative). Bidirectional analog switch common connected via internal switch to HSD1- or HSD2- depending on S/OE. Rail-to-rail I/O and tolerates VBUS short.
5	GND	power_in	Ground reference (0V). Connect to system ground plane.
6	HSD1-	bidirectional	Multiplexed source input for the negative USB data line, channel 1. Connected to D- when S=0 and /OE=0 (RON ≈ 5Ω typ at 3.0V).
7	HSD1+	bidirectional	Multiplexed source input for the positive USB data line, channel 1. Connected to D+ when S=0 and /OE=0 (RON ≈ 5Ω typ at 3.0V).
8	HSD2-	bidirectional	Multiplexed source input for the negative USB data line, channel 2. Connected to D- when S=1 and /OE=0.
9	HSD2+	bidirectional	Multiplexed source input for the positive USB data line, channel 2. Connected to D+ when S=1 and /OE=0.
10	/OE	input	Active-low Output Enable. When /OE=1, all switches are OFF (high-Z) regardless of S. When /OE=0, S selects channel 1 or channel 2. Digital CMOS input.
