DTMF GENERATORS

DESCRIPTION

The SC9200A/B tone generators are designed for µC interfaces.

They can be instructed by a µC to generate 16 dual tones and 8

single tones from the DTMF pin. The SC9200A provides a serial

mode whereas the SC9200B contains a selectable serial/parallel

mode interface for various applications such as security systems,

home automation, remote control through telephone lines

communication system, etc.

FEATURES

* Operating voltage: 2.0V~5.5V

* Serial mode for the SC9200A

* Serial/parallel mode for the SC9200B

* Low standby current

* Low total harmonic distortion

* 3.58MHz crystal or ceramic resonator

DIP-8
