HT9170D – 2.5V To 5.5V DTMF Receiver IC – DIP18

HT9170D – 2.5V To 5.5V 3.58MHz Resonator DTMF Receiver IC – SOP-18 Package

The HT9170D are Dual Tone Multi Frequency (DTMF) receivers integrated with digital decoder and bandsplit filter functions as well as power-down mode and inhibit mode operations. Such devices 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 implemented to divide tone signals into low and high group
signals. A built-in dial tone rejection circuit is provided to eliminate the need for pre-filtering.  Sharvielectronics Tags, HT9170B, HT9170D, HT9170D-18SOPLF, HT9170, DTMF Receiver, DTMF Driver IC, DTMF Receiver IC.
