DTMF decoders |
|
|
I am searching for a DTMF decoder chip.
The 8870 was the device of choice, but that kind of gives away my age, as
it is obsolete.
icmaster.com sends me off looking for several:
TSC75T204 TDK
CD22204 Intersil
and a couple others I cannot recall, and each manufacturers website comes
up with nothing on a search. I am a contract designer, and new to the
area, so I don't have a lot of sales contacts yet to help push this chase
down the road. Digikey, Mouser, et al don't seem to have any DTMF chips.
Does anyone have knowledge or suggestions for a DTMF tone detector IC that
is actually available?
Thanks a lot for any input.

The 8870 is still available. |
Try Zarlink - http://www.zarlink.com/ and

Definitely not obsolete. I just bought 840 of them in SOIC format.
