TS5A23157DGSR from Texas Instruments, 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	IN1	input	Select pin for switch 1. Digital control input (5-V tolerant) chooses between the NC1 and NO1 signal paths to COM1. VIH = V+ × 0.7, VIL = V+ × 0.3.
2	NO1	bidirectional	Normally open analog I/O for switch 1. Connected to COM1 when IN1 selects the NO path; signals pass bidirectionally through the ~10-Ω on-resistance path.
3	GND	power_in	Ground reference for the device. All analog and digital voltages are referenced to this pin.
4	NO2	bidirectional	Normally open analog I/O for switch 2. Connected to COM2 when IN2 selects the NO path; signals pass bidirectionally through the ~10-Ω on-resistance path.
5	IN2	input	Select pin for switch 2. Digital control input (5-V tolerant) chooses between the NC2 and NO2 signal paths to COM2. VIH = V+ × 0.7, VIL = V+ × 0.3.
6	COM2	bidirectional	Common analog I/O for switch 2. Routed to either NC2 or NO2 depending on the state of IN2.
7	NC2	bidirectional	Normally closed analog I/O for switch 2. Connected to COM2 when IN2 is low; signals pass bidirectionally through the ~10-Ω on-resistance path.
8	V+	power_in	Positive supply pin. Recommended operating range 1.65 V to 5.5 V; absolute maximum 6.5 V. Bypass locally to GND with a small ceramic capacitor.
9	NC1	bidirectional	Normally closed analog I/O for switch 1. Connected to COM1 when IN1 is low; signals pass bidirectionally through the ~10-Ω on-resistance path.
10	COM1	bidirectional	Common analog I/O for switch 1. Routed to either NC1 or NO1 depending on the state of IN1.
