U74AHC1G04G-AL5-R from UTC Unisonic Tech, 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 | NC | unconnected | No connect. Leave floating or tie to a stable potential; not internally bonded. |
| 2 | A | input | Logic input to the inverter. Valid VIH ≥ 3.85V at VCC=5.5V; VIL ≤ 1.65V at VCC=5.5V. Input leakage ±0.1μA max, input capacitance 2pF typ. |
| 3 | GND | power_in | Ground reference (0V) for the device. Tie to system ground. |
| 4 | Y | output | Inverted logic output (Y = /A). Rail-to-rail CMOS output with ±8mA drive at VCC=5V (VOH ≥ 3.94V, VOL ≤ 0.36V at IOH/IOL=8mA, VCC=4.5V). |
| 5 | VCC | power_in | Positive supply voltage, 2V to 5.5V operating range (7V absolute maximum). Decouple to GND with a 0.1μF ceramic capacitor close to the pin. |
