SN74LVC1G07QDCKRQ1 from Texas Instruments, in a SC-70-5. 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	Not connected. No internal connection; leave floating or tie to a fixed potential per board practice.
2	A	input	Buffer input. CMOS logic input, 5.5 V-tolerant regardless of VCC. Drives the open-drain output Y (Y = A per the function table: A=L → Y=L, A=H → Y=Hi-Z).
3	GND	power_in	Ground reference for the device (0 V).
4	Y	output	Open-drain buffer output. Sinks up to 32 mA (IOL max at VCC = 4.5 V). Requires an external pull-up to VPU (≤ 5.5 V); can be wired-OR/AND with other open-drain outputs.
5	VCC	power_in	Supply voltage. Operating range 1.65 V to 5.5 V; data-retention 1.5 V min. Bypass with 0.1 µF close to the pin.
