I need a DTMF tone generator and decoder for a project but dont know the part number. I have seen some part#s like CD22202 but cant get them from ahy where May I also know if the normal telephone contains the generator and decoder may be in one package ? I have some old phones which contains an IC numbered HM 9100A1. Thankx in advance.
Telephones contain a dtmf generator, but not a decoder.
If you have not used Google to search for dtmf generator and dtmf decoder, you should do that now.
