TC74HC14AF Applications：

Signal Conditioning: It’s commonly used to clean up noisy digital signals by converting them into a clean square wave.

Oscillator Circuits: It can be used in conjunction with other components to build simple oscillator circuits.

Logic Level Shifting: It can also be used to shift logic levels from one voltage to another, for example, from 5V TTL logic to 3.3V CMOS logic or vice versa.

Waveform Shaping: The Schmitt trigger functionality helps in shaping the input waveform, especially if there is noise or distortion.

Clock Signal Generation: It can generate clock signals in digital circuits.

Buffering: It can act as a buffer between different parts of a digital circuit to prevent loading effects.

Pulse Shaping: It can be used to shape input pulses to have a specific rise and fall time.
