hello
I'm doing a project which has a 3 digit 7 segment display in it. I'm using IC 7447 (bcd to 7seg)for it. the bcd code is fed from 7490 ic(decade counter). The problem is, sometimes, the value shown by the display goes erratic..changing quickly to values like 521 etc from low values like 6 or 7 etc.
What could be the problem? could there be something wrong with the counter IC? or some loose connections in the display ckt?
thanks
