I'm looking for a DTMF encoder ic and a matching DTMF decoder IC.
The ones I have seen use a serial interface bus but I am after discreet
I am aware of the Motorola MC145436 but it seems that this chip is going out
of fashion. (Farnell and RS dont stock it any more)
Re: SOIC DTMF IC encoder and decoder needed
There are number of decoder chips listed at
some of which might actually be obtainanable, but ye olde Mitel 8870/880 series
were certainly the classical units for this.
