Before diving into calculations, we must understand why the 74HC14 oscillates so readily.

A list of common 74HC14 oscillator calculator tools: ) generated by the 74HC14

: Because it is an inverter, a LOW input results in a HIGH output (approximately equal to the supply voltage, VCCcap V sub cap C cap C end-sub

At very high frequencies (approaching 10 MHz), the internal propagation delay of the inverter (approx 15–30 ns) becomes a significant fraction of the period. A full calculator must include a term for ( t_pd ).
