Hi,
Your SIEMENS parts are obsolete but are common CMOS functions.
FZH111 is a quad 2 input nand n-input
FZJ111 is a JK-flip-flop with n-input
Hope this gets you started in the right direction. If I can help you locate the SIEMENS parts let me know.

Ed,
We have helped a small company with a parts selection tool and cleaned up their database in the process. We are currently working on developing a BOM intagration tool to inteface with the selection tool. This solution has many phases and might help you as well. I would be happy to share...
