I am hobbyist and am looking to reduce signal frequency using D type flip flops. I have a circuit diagram for a 4013 IC but I would like to use a 74HC74 instead and I do not understand if it is possible.
- 7474 are dual D positive edge triggered flip-flop, asynchronous preset and clear.
- 7479 is a dual D flip-flop
Likewise the 4000 series:
- 4013 is a Dual D Type Flip Flop
From looking at the functional diagram in the specifications, they are essentially the same other then that one has CD [asynchronous clear-direct input (active HIGH)] and the other has RD [asynchronous reset-direct input (active LOW)] on the diagram.
Could this be done using 74HC74? How would such a circuit be different? or can RD be connected to the negative wire just like CD?
