#140519 - HC or AC gate input
Responding to: ???'s previous message
I dont think that it will work.
Many times we try checking Oscillator working with mutimeter
probe and then the uC oscillation stop with that load of Capacitance + say 10M ohm of impedance.
Also the HC types are not so good for working above 12MHz.
You have to have those AC or ALS which are capable of working
upto 30MHz. Nobody will want to use 74S types which can guarantee to bog down oscillator with its load.
There is way to check the performance of oscillator with
small value ~ 30pf trimmer cap.

      What I want is the result, not speculation            01/01/70 00:00      
         why 'test', why 'speculate'            01/01/70 00:00
