SN74AHC1G125DC 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 | OE | input | Output enable input; a high level on OE puts output Y in the high-impedance state, and a low level enables the buffer (A to Y). |
| 2 | A | input | Data input of the non-inverting buffer; recommended input voltage range is 0 V to 5.5 V (absolute maximum -0.5 V to 7.0 V). |
| 3 | GND | power_in | Ground (0 V). |
| 4 | Y | tri_state | Buffered data output with three-state capability; output current is limited to ±25 mA (absolute maximum) and output voltage must stay between 0 V and VCC. |
| 5 | VCC | power_in | Supply voltage; recommended 2.0 V to 5.5 V for SN74AHC1G125 and 4.5 V to 5.5 V for SN74AHCT1G125 (absolute maximum 7.0 V). |
