* Operating voltage: 2.0V~5.5V * Serial mode for the SC9200A/AS * Serial/parallel mode for the SC9200B/BS * Low standby current * Low total harmonic distortion * 3.58MHz .

DIP-8 SOP-8 FEATURES * Operating voltage: 2.0V~5.5V * Serial mode for the SC9200A/AS * Serial/parallel mode for the S.

The SC9200 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/AS provides a serial mode whereas the SC9200B/BS contains a selectable serial/parall.
