First of all, sorry if this question has already been asked, I am a new user of the application and new to digital electronics altogether.
I am supposed to make a 4-bit counter using SN7475, to count up/down when pushing a button. http://circuits.datasheetdir.com/105/SN7475-pinout.jpg
And I do not know where to start. How to make the D latches for the connections? Any tips would be great. Thanks guys.
