SC9200A/B
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
