Diodes Incorporated · Inverters · SOT-353

74AHC1G14QSE-7 from Diodes Incorporated, 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 connection.
2 A input Schmitt-trigger data input, not limited by VCC, accepts 0 to 5.5V and unused inputs should be held at VCC or ground.
3 GND power_in Ground.
4 Y output Push-pull inverted data output, rated for ±8mA drive at VCC = 4.5V to 5.5V.
5 VCC power_in Supply voltage, recommended 2V to 5.5V (absolute maximum -0.5 to 6.5V).
