SN74LVC1G14DC from lingxingic, 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 | n.c. | unconnected | Not connected (不连接); the datasheet gives no internal connection for this pin. |
| 2 | A | input | Data input; recommended input voltage is 0 V to 5.5 V, and the absolute maximum input voltage is -0.5 V to +6.5 V. |
| 3 | GND | power_in | Ground (0 V) reference for the device. |
| 4 | Y | output | Data output (inverting Schmitt-trigger output, Y = NOT A); output current is limited to ±50 mA absolute maximum, and in operating mode the output voltage must stay between 0 V and VCC. |
| 5 | VCC | power_in | Supply voltage; recommended range is 1.65 V to 5.5 V, with an absolute maximum of -0.5 V to +6.5 V. |
