74AUP1T34SE-7 from Diodes Incorporated, in a SOT-353. 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 | VCCA | power_in | A-side supply rail (0.9V to 3.6V, absolute max -0.3 to +4.0V). Sets the input switching thresholds on pin A. When VCCA = 0V, the Y output enters high-impedance (three-state). |
| 2 | A | input | Data input to the non-inverting buffer/translator; switching thresholds referenced to VCCA (0.9V to 3.6V). ~100 mV typical hysteresis, input current ±1 µA max. May be left floating when VCCB = 0V (input circuitry disabled). |
| 3 | GND | power_in | Device ground reference (0V) for both VCCA and VCCB supply domains. |
| 4 | Y | tri_state | Data output of the buffer; VOH tracks VCCB (0.9V to 3.6V), ±6 mA output drive at 3V. Enters high-impedance (three-state) when VCCA = 0V or VCCB = 0V (IOFF partial power-down). |
| 5 | VCCB | power_in | B-side supply rail (0.9V to 3.6V, absolute max -0.3 to +4.0V). Sets the output high level (VOH) on pin Y. When VCCB = 0V, the A-side input circuits are disabled (IOFF). |
