74AUP1T34QSE-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 | VCCA | power_in | Supply for input pin A, operating from 0.9 V to 3.6 V. |
| 2 | A | input | Data input with switching thresholds referenced to VCCA, and input voltage absolute maximum range of -0.5 V to +4.6 V. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | Y | tri_state | Data output with HIGH level tracking VCCB; it is three-state when VCCA is 0 V, and output voltage absolute maximum range is -0.5 V to +4.6 V. |
| 5 | VCCB | power_in | Supply for output pin Y, operating from 0.9 V to 3.6 V. |
