1MHz Signal

(Divided down from 4MHz)




There are several projects involving CPU clocks and this is another but with a faster Rise Time of 5 to 6ns which makes it suitable for WD's 65c02..


Setting Up Your System:

The documentation on the 74HC590 from TI, Philips and Nexperia all provide some basic info on cascading the devices. The docs suggest one method for 2 ICs and another method for 3 or more ICs. I chose the latter which works fine with two '590s.
