74AHCT2G125DC from Nexperia, in a VSSOP-8-0.5mm. 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 | 1OE | input | Output enable input for buffer 1, active LOW; when HIGH, output 1Y is forced to the high-impedance Z state. |
| 2 | 1A | input | Data input for buffer 1; inputs are overvoltage tolerant to 5.5 V. |
| 3 | 2Y | tri_state | Data output of buffer 2; follows 2A when 2OE is LOW and is high-impedance (Z) when 2OE is HIGH. |
| 4 | GND | power_in | Ground reference, 0 V. |
| 5 | 2A | input | Data input for buffer 2; inputs are overvoltage tolerant to 5.5 V. |
| 6 | 1Y | tri_state | Data output of buffer 1; follows 1A when 1OE is LOW and is high-impedance (Z) when 1OE is HIGH. |
| 7 | 2OE | input | Output enable input for buffer 2, active LOW; when HIGH, output 2Y is forced to the high-impedance Z state. |
| 8 | VCC | power_in | Supply voltage: 2.0 V to 5.5 V for 74AHC2G125 and 4.5 V to 5.5 V for 74AHCT2G125 (Table 6). |
