74LVC1G126QSE-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; a LOW level puts the Y output in the high-impedance state, input tolerant to 5.5V. |
| 2 | A | input | Data input, tolerant to 5.5V; unused inputs should be held at VCC or ground. |
| 3 | GND | power_in | Ground. |
| 4 | Y | tri_state | 3-state data output (non-inverting) with ±24mA drive at 3.3V, high-impedance when OE is LOW. |
| 5 | VCC | power_in | Supply voltage, 1.65V to 5.5V operating range. |
