74AHCT1G125DBVTG4 from Texas Instruments, 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; when high, disables tri-state output Y to high-impedance state; when low, data passes from input A to output Y |
| 2 | A | input | Data input A with TTL-level thresholds VIL=0.8V and VIH=2V; input voltage range 0V to 5.5V |
| 3 | GND | power_in | Ground pin at circuit reference potential (0V) |
| 4 | Y | tri_state | Tri-state data output; passes buffered input A when OE is low with drive ±8mA at 5V; disabled to high-impedance state when OE is high; output voltage 0V to VCC |
| 5 | VCC | power_in | Positive power supply pin; operating range 4.5V to 5.5V; maximum quiescent current 10µA |
