74LVC1G126SE-7 from Diodes Incorporated, in a SOT-353. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OE | input | Output enable, active HIGH; when held LOW the Y output goes to high impedance (Z) per the function table. |
| 2 | A | input | Data input; inputs are tolerant up to 5.5 V, allowing mixed-voltage operation. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | tri_state | Buffered data output with 3-state capability; high impedance when OE is LOW, and Y follows A when OE is HIGH. |
| 5 | VCC | power_in | Supply voltage, operating range 1.65 V to 5.5 V. |
