Hi RonIn the Digital Component selection window, there is the behavioral xjkflop. See the Help file under Special Functions for instructions on how to use behavioral digital components. Some of this is undocumented. Come back with any questions you have.
In the CD4000 library, there is CD4027.
In the 74HC library, there is 74HC107 and 74HC109. Also see the 74HCT library.
See screen captures of these windows in the attachments below.
The behavioral digital components are installed with LTspice when you first download it. If you don't have the other libraries, get them from the Yahoo LTspice group. You will have to join first.

I cannot access the xjkflop as it is not in my library, what can I do?
Having difficulty accessing the links. Are they still valid?Join the Yahoo LTspice group (it's free). Then go to this page:

Open xjkflop.asy with Notepad, and save it to /lib/sym/digital.
Then open JKFF 4bit counter.asc with LTspice. This is an example of how to use the xjkflop.
