I'm doing a project in my digital systems class where I need to divide a 10 khz clock pulse down to 1 hz. I thought I would use 4 cascaded decade counters for the job.
Then I found this one: SN74LS90N
But I can't figure out how to cascade 4 of these together, because I don't see any ripple carry or terminal count output. No enable input either for that matter.
Does that mean they can't be cascaded? Or is there some simple way of solving it?
Thanks
