SN74LVC1GU04DBVR from Texas Instruments, 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	unconnected	No internal connection. Can be left floating or tied to VCC/GND for layout convenience.
2	A	input	Logic input to the unbuffered inverter. Accepts input voltages up to 5.5 V independent of VCC. VIH = 0.75 x VCC, VIL = 0.25 x VCC.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	Unbuffered inverter output, Y = /A. Provides ±24 mA drive at VCC = 3 V (up to ±32 mA at 4.5 V).
5	VCC	power_in	Positive supply voltage. Recommended operating range 1.65 V to 5.5 V; absolute max 6.5 V.
