74HC04 Oscillator Evaluation

Various 74HC04 Based Oscillator Configurations

Just how good is the 74HC04 as an oscillator?

How high in frequency will it go?

How stable is it?

What is the best oscillator configuration?

Several crystal and LC oscillators have been built with the 74HC04 CMOS logic gate, but all use the same "standard" configuration. There has always been some question regarding other possible circuit configurations, and possibly fine-tuning the amount of feedback, circuit impedances, etc. This web page is a start at answering some of the questions.
