SN74LVC3G34DCTR from Texas Instruments, in a MSOP-8-2.8mm. 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	1A	input	Buffer 1 input. CMOS logic input; accepts up to 5.5 V regardless of VCC (down-translation supported).
7	1Y	output	Buffer 1 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V.
3	2A	input	Buffer 2 input. CMOS logic input; accepts up to 5.5 V regardless of VCC.
5	2Y	output	Buffer 2 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V.
6	3A	input	Buffer 3 input. CMOS logic input; accepts up to 5.5 V regardless of VCC.
2	3Y	output	Buffer 3 output. Y = A. Push-pull CMOS output rated ±24 mA drive at VCC = 3.3 V.
4	GND	power_in	Device ground reference. Connect to system 0 V.
8	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V data-retention minimum). Decouple locally to GND with a 0.1 µF ceramic.
