HT9170 is an decoding intergrated circuit of two-tone caller display,which iswidely used in wireless or wiring phones with caller display. 1.pin functions and relevent data HT9170 intergrated circuits are pinned in dual in-line package with 18-lead, whose pin functions and relevent data are listed in Figure 11. 2.intergrated ciucuits of the same type The decoding intergrated circuits of caller display usually used by DTMF:CS9370DGP,HM9270C, TH3170D,HM9270D and HT9l70HT9270D. The pin sequences and functions of these 6 circuits are almost the same, and all of their pin functions and relevent data are listed in Table 1-1.
