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
