74LVC1G34W5-7 from Diodes Incorporated, in a SOT-25. 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 | NC | unconnected | No connection. Not internally bonded; may be left floating or tied to any potential within absolute maximum ratings. |
| 2 | A | input | Data input to the buffer gate. CMOS/TTL-compatible logic input, 5.5V-tolerant regardless of VCC. Drives output Y such that Y = A. VIH depends on VCC (e.g. 2V min at VCC = 3.0V-3.6V); input current ±1μA max. |
| 3 | GND | power_in | Ground reference (0V). Return path for supply and output currents; continuous current through GND rated ±100mA absolute max. |
| 4 | Y | output | Data output of the buffer gate (Y = A). Push-pull CMOS output; ±24mA drive at VCC = 3.3V (up to ±32mA at 4.5V). Output is disabled by the IOFF circuitry when the device is powered down to prevent current backflow. |
| 5 | VCC | power_in | Positive supply voltage input. Operating range 1.65V to 5.5V (data retention only down to 1.5V). Absolute max -0.5V to 6.5V. Bypass with a decoupling capacitor close to the pin. |
