74AHC1G125QSE-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 input; a HIGH level applied to OE places output Y in the high-impedance state. |
| 2 | A | input | Data input with Schmitt-trigger action, with recommended input voltage range 0 to 5.5 V. |
| 3 | GND | power_in | Ground reference pin. |
| 4 | Y | tri_state | Three-state data output with ±8 mA drive at VCC = 5 V ±0.5 V. |
| 5 | VCC | power_in | Supply voltage pin with recommended operating range of 2 V to 5.5 V. |
