74HC 14 is a high-speed CMOS device, and its pins are compatible with low-power Schottky TT 1 (1st 1) series. A 6-channel Schmitt trigger inverter is implemented, which can convert a slowly changing input signal into a clear jitter-free output signal.

It can be applied to waveform, pulse shaper, unstable multivibrator, monostable multivibrator and so on.
