TS12A12511DCNR from Texas Instruments, in a SOT-23-8. 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	COM	bidirectional	Common analog switch terminal. Bidirectional analog I/O; connects to NC when IN is low and to NO when IN is high. Rail-to-rail signal range (-VCC to +VCC), 5 Ω typical RON.
2	NC	bidirectional	Normally-Closed analog switch terminal. Bidirectional analog I/O connected to COM when the IN control input is low. Handles rail-to-rail signals within the -VCC to +VCC range.
3	GND	power_in	Ground (0 V) reference for the device.
4	V+	power_in	Most positive power supply (VCC). Recommended operating range 0 V to 12 V single-supply, or +5 V for ±5 V dual supply. Absolute maximum 13 V vs GND.
5	N.C.	unconnected	No connect. Not internally connected; may be left floating or tied to any potential.
6	IN	input	Logic control input that selects the switch path. IN low = COM connected to NC; IN high = COM connected to NO. VIH ≥ 2.4 V, VIL ≤ 0.8 V (5-V supply); compatible with 3.3-V and 5-V CMOS logic. Input current ±1 µA max.
7	V-	power_in	Most negative power supply (-VCC). Recommended operating range -6 V to 0 V. Used in dual-supply applications; MUST be tied to GND in single-supply applications.
8	NO	bidirectional	Normally-Open analog switch terminal. Bidirectional analog I/O connected to COM when the IN control input is high. Handles rail-to-rail signals within the -VCC to +VCC range.
