Hi ,
i am having problem working with UM91214b IC (DTMF generator IC ).

Can you suggest some other commonly available DTMF IC ,and its reciever.

You can also suggest me some circuit that you've tested with UM91214b.

I am using it for remote control application.

Thanks !!

UMC is not more available, you can use the universal MT8880 , encoder & decoder, in the net you can find many source code for drive it
