74AHC1G09QSE-7 from Diodes Incorporated, in a SOT-353. 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	Data input A of the 2-input AND gate. Schmitt-trigger CMOS input; input voltage range 0 to 5.5V, tolerant of slow rise/fall times. Not limited by VCC.
2	B	input	Data input B of the 2-input AND gate. Schmitt-trigger CMOS input; input voltage range 0 to 5.5V, tolerant of slow rise/fall times. Not limited by VCC.
3	GND	power_in	Ground reference (0V). Continuous current through GND is rated at -75mA maximum.
4	Y	output	Open-drain data output implementing Y = A · B. Requires an external pull-up resistor to achieve the high-level state. Sinks 8mA at VCC = 4.5V (VOL <= 0.36V typ) and 4mA at VCC = 3.3V.
5	VCC	power_in	Positive supply voltage input. Operating range 2.0V to 5.5V; absolute maximum -0.5V to 6.5V. Supply current ICC is 1µA max at 25°C, up to 40µA over -40 to +125°C.
