74AHCT1G125GW from Nexperia, in a SOT-353. 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 | OE | input | Active-LOW output enable input. When LOW, the output Y follows input A; when HIGH, Y is placed in the high-impedance (3-state) OFF state. TTL-compatible input (VIH >= 2.0 V, VIL <= 0.8 V at VCC = 4.5-5.5 V), overvoltage tolerant to 5.5 V. |
| 2 | A | input | Data input to the buffer. TTL-compatible logic input (VIH >= 2.0 V, VIL <= 0.8 V at VCC = 4.5-5.5 V). Overvoltage tolerant up to 5.5 V regardless of VCC, enabling voltage translation. |
| 3 | GND | power_in | Ground reference (0 V). All voltages in the datasheet are referenced to this pin. |
| 4 | Y | tri_state | Buffered 3-state data output. Drives HIGH/LOW following A when OE is LOW, and enters high-impedance OFF state when OE is HIGH. Rated for +/-8 mA drive at VCC = 4.5 V (VOH >= 3.94 V, VOL <= 0.36 V typical). |
| 5 | VCC | power_in | Positive supply voltage. Operating range 4.5 V to 5.5 V for the 74AHCT1G125 (TTL-input) variant; absolute maximum 7.0 V. Decouple to GND with a local ceramic capacitor. |
