SN74LVC1G125DB from lingxingic, 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 | OE | input | Output enable input (active low): when OE is low the output Y follows A, and when OE is high Y is forced to high-impedance (Z), per the function table. |
| 2 | A | input | Data input; the input accepts 3.3V or 5V logic levels, and the recommended input voltage range is 0 to 5.5V. |
| 3 | GND | power_in | Ground reference (0V). |
| 4 | Y | tri_state | Three-state data output, with ±24 mA output drive at VCC=3.0V; the output is high-impedance when OE is high. |
| 5 | VCC | power_in | Supply voltage; the recommended range is 1.65V to 5.5V, and the absolute maximum is -0.5V to +6.5V. |
