SN74LVC3G34DCUR from Texas Instruments, in a VSSOP-8. 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. Accepts voltages up to 5.5 V regardless of VCC (can be used as a down translator).
7	1Y	output	Buffer 1 output. Non-inverting output of 1A (Y = A). Drives ±24 mA at VCC = 3.3 V.
3	2A	input	Buffer 2 input. Accepts voltages up to 5.5 V regardless of VCC.
5	2Y	output	Buffer 2 output. Non-inverting output of 2A. Drives ±24 mA at VCC = 3.3 V.
6	3A	input	Buffer 3 input. Accepts voltages up to 5.5 V regardless of VCC.
2	3Y	output	Buffer 3 output. Non-inverting output of 3A. Drives ±24 mA at VCC = 3.3 V.
4	GND	power_in	Ground reference for the device.
8	VCC	power_in	Supply voltage. Operating range 1.65 V to 5.5 V (data retention only down to 1.5 V). Bypass with a decoupling capacitor to GND.
