Default Multifunction IC

Hello, first thanks for your comments and suggestions, and
sorry for my tri-post...sometimes thunderbird combined with my nerves
make for such nasty things.
Regarding the IC, please look at:

and you will see a CW keyer build around a single IC (MC787P in this case).
So yes, such a rare beasts exist ...lol. They consist of a J-K flip-flop
and 2 or 3 gates. The problem is that they are dated back from the 70's
and doesn't exist anymore, so I was looking for a more current one.
Thanks anyway and happy new year !!

Andrew.
