TS5A3166DBVR-TP from TECH PUBLIC, in a SOT-23-5. 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	NC	passive	Normally-Closed switch terminal. Connected to COM when the IN control input is logic low; disconnected when IN is high. Bidirectional analog signal path, rated -0.3 V to +6.5 V, ±50 mA continuous.
2	COM	passive	Common switch terminal. Routed to the NC pin when IN is logic low. Bidirectional analog signal path, rated -0.3 V to +6.5 V, ±50 mA continuous; on-resistance typ. 3.3 Ω at VA = 4.0-5.5 V.
3	GND	power_in	Ground reference for the supply and the digital control logic.
4	IN	input	Digital control input for the switch. Logic low turns the switch ON (COM connected to NC); logic high turns it OFF. 1.8 V-logic compatible: VIH ≥ 1.4 V at VCC = 1.5-3.3 V (≥1.6 V at VCC = 3.3-5.5 V); VIL ≤ 0.4/0.6 V.
5	VCC	power_in	Positive supply voltage. Operating range 1.5 V to 5.5 V (recommended 1.6-5.5 V); absolute max 6.5 V. Typical quiescent current <2 µA.
