dialer chip NTE1691

[lerameur]

Hello,

I would like to use a dialer chip the NTE1691. Can some tell me how to
use the RC pin, There a three pins used ar reference frequency, The
datasheet does not say how to hook them up (RC), and also it do not
talk about the output frequencies for dialing.

anyone has a circuit configuration.. a schematic or a better
datasheet
thank you
ken

If it doesn't tell you how to hook it up, then that's it.

NTE is a replacement line, intended to replace existing components.
You look the part up in the cross-reference, find their part, and
pay good money to buy it. The price is a premium to help ensure
you can get it locally, and you're paying for the cardboard that
makes it so easy to handle.

But if NTE doesn't have information about using it, and they never
put "sample circuits" in the replacement guides I have, then you have
to either abandon the project, or find a device that the NTE device
replaces, and get the datasheet for that original device.

The most accessible method of getting a dialer (I'm assuming you
are talking about telephone dialer), then buy a cheap telephone,
and either use it intact or extract the dialing part. You don't
really need data, since the external components are connected up,
and that will tell you how it's supposed to be hooked up. INdeed,
there is little reason to just pull the IC, you might as well
carve out a chunk of the board (if for whatever reasons you can't
leave the phone intact) and use it as a module.

http://www.nteinc.com/Web_pgs/device_list.html takes you directly to
the NTE website's list of all available data sheets.

ECG had a three volume set of databooks with sample circuits, but NTE
apparently dropped them when they bought out their competitor. NTE used
the same numbering system as ECG. Sylvania's ECG line was well
established, and the leader in the industry, until Sylvania was bought
out. NTE started by selling some parts offered by ECG, and simply
copying the cross reference data from the ECG book.
