NC7S02M5X from onsemi, 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	A	input	Logic input A of the 2-input NOR gate. CMOS input, VIH = 0.7VCC, VIL = 0.3VCC (VCC >= 3 V). Must not float; tie HIGH or LOW when unused.
2	B	input	Logic input B of the 2-input NOR gate. CMOS input, VIH = 0.7VCC, VIL = 0.3VCC (VCC >= 3 V). Must not float; tie HIGH or LOW when unused.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	NOR gate output, Y = NOT(A + B). Balanced push-pull CMOS drive of +2 mA IOH / -2 mA IOL at VCC = 4.5 V.
5	VCC	power_in	Positive supply, 2.0 V to 6.0 V recommended operating range (absolute max 7.0 V). Quiescent supply current ICC < 1 uA typ.
