The HT9170 is a Dual Tone Multi Frequency (DTMF) receiver integrating a digital decoder and bandsplit filter functions. The HT9170B and HT9170D devices can enter the power down mode. The HT9170 series all use the digital counting techniques to detect and decode the 16 kinds of DTMF input into a 4-bit code output. Highly accurate filter circuits are implemented to divide tone signals into high frequency and low frequency signal.
Features:
- Operating voltage: 2.5V~5.5V
- Minimal external components
- No external filter is required
- Low standby current (on power down mode)
- Tristate data output for µC interface
- 3.58MHz crystal or ceramic resonator
- 1633Hz can be inhibited by the INH pin
