>I couldn't get the 74f74 d-flip flop, but got a 74als74 instead. I was told ^^^ >that it would function just as the 74f74 would (i.e. pos. edge), but I >couldnt get the thing to work properly.

I mean, is >there something about the 74als74 that is different from the 74f74? Yes, the 74als74 is slower than the 74f74. The 74als74 probably delayed the clock signal too much. >Bob Fahey > >| ///| a.k.a.
