74LVC1G34LT05ARCQ from GR, in a SOT-23-5. 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 internal connection; leave unconnected. |
| 2 | A | input | Logic input of the buffer (Y = A); inputs accept voltages up to 5.5 V per the datasheet features. |
| 3 | GND | power_in | Ground reference, 0 V. |
| 4 | Y | output | Buffered logic output (Y = A) with ±24 mA drive at 3.3 V; continuous output current is limited to ±50 mA absolute maximum. |
| 5 | VCC | power_in | Supply voltage, 1.65 V to 5.5 V operating, with 6.5 V absolute maximum. |
