TC7SH34FU from TOSHIBA LJ CT, 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	NC	unconnected	No connection. Not internally bonded; leave floating or tie as convenient for layout.
2	IN A	input	Buffer logic input A. CMOS input with 5.5 V tolerance; VIH ≥ 0.7·VCC (min), VIL ≤ 0.3·VCC (max). Drives the non-inverting output Y (Y = A).
3	GND	power_in	Ground / 0 V reference for the device.
4	OUT Y	output	Non-inverting buffer output Y (Y = A). Push-pull CMOS output; VOH ≥ 3.94 V at IOH = -8 mA (VCC = 4.5 V), VOL ≤ 0.36 V at IOL = 8 mA (VCC = 4.5 V).
5	VCC	power_in	Positive supply voltage. Operating range VCC = 2.0 V to 5.5 V; absolute max 7.0 V. Bypass with a local decoupling capacitor to GND.
