From: Mike on 28 Jan 2006 13:24 I'm looking for DTMF decoder chips and I am having a lot of trouble finding any. Some of the part numbers I have searched are TDK's SSI-220, or G8870 Any available DTMF decoder will do the job. Does anyone know a place where I could definetly find some? Thanks
From: Mario Chenier on 28 Jan 2006 14:59 Mike: try Zarlink (previously Mitel) MT8880 (DTMF transceiver) or MT8870 (DTMF receiver). Finding them in unit quantities may be a problem. Digi-Key does not have it in stock, nor does Electrosonic. Mouser does not carry the line. Avnet has stock of some models of the 8870 and the 8880. Mario.

Does anyone know a place >where I could definetly find some? Even my local (Perth, Australia) parts supplier has them in stock, $A2.20. Forget the prefix, 8870 is the generic part number to search for. |
