# 74AHC1G14GW

**TECH PUBLIC** · Logic Gates · SOT-353

74AHC1G14GW from TECH PUBLIC, 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 connect pin; not internally connected to the device function. |
| 2 | A | input | Schmitt-trigger inverter input; recommended input voltage 0 to 5.5V, with Y = inverse of A. |
| 3 | GND | power_in | Ground pin, 0V reference for the supply. |
| 4 | Y | output | Inverted output of input A, driving ±8mA at 5V, with output voltage range 0 to VCC. |
| 5 | VCC | power_in | Supply voltage pin, recommended operating range 2V to 5.5V (absolute maximum -0.5 to 7V). |
