This positive feedback – typical of Schmitt trigger behaviour – ensures rapid, clean switching of the digital output signal. Buffers IC3A and IC3B are necessary (particularly at high frequencies) to ...

Assuming you want a Schmitt trigger in a circuit, you have plenty of options. There are ICs like the 74HC14 that include six (inverting) Schmitt triggers. On a schematic, ...

This beeper circuit will generate an car-splitting 110dB from 9V. The setup uses a single 74C14 (CD40106B) CMOS hex inverting Schmitt-trigger IC, which must be used with a piezoelectric device with a ...
