74LVC1G34SE-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 | NC | unconnected | No connection internally. |
| 2 | A | input | Data input that accepts 0 to 5.5V regardless of VCC, and unused inputs should be held at VCC or ground. |
| 3 | GND | power_in | Ground pin; continuous current through VCC or GND is limited to ±100mA. |
| 4 | Y | output | Push-pull data output (Y = A) that drives ±24mA at VCC = 3.3V and is disabled by IOFF circuitry when the device is powered down. |
| 5 | VCC | power_in | Supply voltage pin with a recommended operating range of 1.65V to 5.5V and an absolute maximum of -0.5 to 6.5V. |
