SN74LVC2G240DCUR 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	1OE	input	Active-low output-enable for buffer 1. When 1OE = L, 1Y follows 1A; when 1OE = H, 1Y is in the high-impedance (Hi-Z) state. Tie to VCC through a pull-up during power up/down to keep 1Y in Hi-Z.
2	1A	input	Buffer 1 data input. Accepts CMOS levels up to 5.5 V (independent of VCC), enabling down-translation from higher-voltage inputs to VCC-level outputs.
3	2Y	tri_state	Buffer 2 non-inverting 3-state output. Drives ±24 mA at VCC = 3.3 V; goes to Hi-Z when 2OE = H.
4	GND	power_in	Ground return for the device. 0 V reference for all inputs and outputs.
5	2A	input	Buffer 2 data input. Accepts CMOS levels up to 5.5 V (independent of VCC).
6	1Y	tri_state	Buffer 1 non-inverting 3-state output. Drives ±24 mA at VCC = 3.3 V; goes to Hi-Z when 1OE = H.
7	2OE	input	Active-low output-enable for buffer 2. When 2OE = L, 2Y follows 2A; when 2OE = H, 2Y is in Hi-Z. Tie to VCC through a pull-up during power up/down to keep 2Y in Hi-Z.
8	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V for data retention only). Bypass locally with a 0.1 µF capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g240dcur.step`	122 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g240dcur-etched.step`	3.0 MB	You want the part with `SN74LVC2G240DCUR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 725 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
