Diodes Incorporated · Inverters · SOT-25

74AHC1G14QW5-7 from Diodes Incorporated, in a SOT-25. 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, with a recommended input voltage of 0 to 5.5V; unused inputs should be held at VCC or ground.
3 GND power_in Ground; continuous current through GND is limited to -75mA.
4 Y output Data output (push-pull, inverted from A) with a recommended output current of ±8mA at VCC = 5V ±0.5V.
5 VCC power_in Supply voltage, 2V to 5.5V recommended operating range with an absolute maximum of 6.5V.
