1MHz Signal

(Divided down from 4MHz)

Description:

There are several projects involving CPU clocks and this is another but with a faster Rise Time of 4 to 5ns which makes it suitable for WD's 65c02 CPU.

Speeds halve downwards from 4MHz to 1/4Hz.

 

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 two ICs and another method for 3 or more ICs.
