General Description
The HT9170 series are Dual Tone Multi Frequency (DTMF) receivers integrated with digital decoder and bandsplit filter functions. The
HT9170B and HT9170D types supply power-down mode and inhibit mode operations. All types of the HT9170 series use digital counting
techniques to detect and decode all the 16 DTMF tone pairs into a 4-bit code output. Highly accurate switched capacitor filters are
employed to divide tone (DTMF) signals into low and high group signals. A built-in dial tone rejection circuit is provided to eliminate the need for pre-filtering.
 
Features & Specifications
  • Wide Operating Voltage
  • Minimal External Components
  • No External Filter Required
  • Low Standby Current
  • Excellent Performance
  • 18pin DIP IC
  • Operating voltage: 2.5V~5.5V
