You should remove your email address from your post. The spambots will find it and pound you relentlessly. Can you post a schematic? How can we respond when we have no earthly clue what you are talking about.

74LS90 is a counter
74LS145 is a binary to decimal decoder with open collector outputs

Was that what you wanted to hear?
