# U74LVC1G14G

**UTC(Unisonic Tech)** · Logic Gates · SOT-353

U74LVC1G14G from UTC(Unisonic Tech), 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 | NC | unconnected | No internal connection; the pin is not connected inside the device. |
| 2 | A | input | Schmitt-trigger data input, with input voltage range 0 to 5.5 V and a positive-going threshold VT+ of 1.16 V max at VCC=1.65 V up to 3.33 V max at VCC=5.5 V. |
| 3 | GND | power_in | Ground pin (0 V reference) for the device. |
| 4 | Y | output | Inverted output Y = NOT A, with ±24 mA output drive at VCC=3.0 V and output voltage range 0 to VCC. |
| 5 | VCC | power_in | Positive supply pin, operating range 1.65 V to 5.5 V with an absolute maximum of 6.5 V. |
