SN74LVC1G04DBVR-MS from MSKSEMI, 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 to the inverter. Drives output Y through Y = NOT(A). CMOS input, VIH = 0.7*VCC (at VCC 3-5.5 V); tolerates 0 V to 5.5 V input range.
2	B	input	Labeled 'B / 输入' in the MSKSEMI pin table for DBV/DCK/DRL/YZP packages, but the SN74LVC1G04 truth table lists only A -> Y, so pin 2 is not functionally used by the inverter and should be tied to a defined logic level or left per application design.
3	GND	power_in	Device ground return. 0 V reference for VCC and all I/O.
4	Y	output	Inverted logic output, Y = NOT(A). Push-pull CMOS output; sources/sinks up to 32 mA at VCC = 4.5 V (IOH = -32 mA, IOL = 32 mA).
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating range; absolute max 6.5 V. Bypass with a 0.1 uF ceramic close to the pin.
