HT9200A/HT9200B -- DTMF Generators
General Description
The HT9200A/B tone generators are designed
for MCU interfaces. They can be instructed by a MCU to generate 16
dual tones and 8 single tones from the DTMF pin. The HT9200A
provides a serial mode whereas the HT9200B contains a selectable
serial/parallel mode interface for various applications such as
security systems, home automation, remote control through telephone
lines, communication systems, etc.
Features
- Operating voltage: 2.5V~5.5V
- Serial mode for the HT9200A
- Serial/parallel mode for the HT9200B
- Low standby current
- Low total harmonic distortion
- 3.58MHz crystal or ceramic resonator
- HT9200A: 8-pin DIP/SOP package
HT9200B: 14-pin SOP package
