SN74LVC3G17DCUR from Texas Instruments, in a VSSOP-8-0.5mm. 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 | Schmitt-trigger input to buffer 1. Positive-going threshold VT+ ≈ 1.87 V (max) and negative-going threshold VT- ≈ 1.14 V (max) at VCC = 3 V, giving typical hysteresis of ~0.87 V. Input voltage range 0 V to VCC, accepts up to 5.5 V regardless of VCC. |
| 7 | 1Y | output | Buffered output of channel 1 (Y = A). Drives ±24 mA at VCC = 3.3 V; capable of ±32 mA at VCC = 4.5 V. Rail-to-rail CMOS output. |
| 3 | 2A | input | Schmitt-trigger input to buffer 2. Same threshold characteristics as 1A (hysteretic input, 0 V to VCC, tolerant up to 5.5 V). |
| 5 | 2Y | output | Buffered output of channel 2 (Y = A). CMOS push-pull output, ±24 mA drive at 3.3 V. |
| 6 | 3A | input | Schmitt-trigger input to buffer 3. Same threshold characteristics as 1A/2A. |
| 2 | 3Y | output | Buffered output of channel 3 (Y = A). CMOS push-pull output, ±24 mA drive at 3.3 V. |
| 4 | GND | power_in | Ground reference for the device. Connect to system 0 V. |
| 8 | VCC | power_in | Positive supply rail. Recommended operating range 1.65 V to 5.5 V; absolute max 6.5 V. Decouple with a local ceramic capacitor (e.g. 100 nF) to GND. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 651 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.
