DTMF receiver for telephones

The BU8874 and BU8874F are DTMF receiver ICs developed for use in telephone answering machines, and convert 16 different types of DTMF signals into 4-bit binary serial data. In addition to a compact 8-pin DIP (BU8874) package,these receivers feature a wide dynamic range, eliminating the need for an 1) Dynamic range of 45dB. (internal AGC)\n2) Power down mode.\n3) 4-bit binary serial data output.\n4) Guard time can be controlled through host microcontroller.\n5) Input pins equipped with hysteresis. (ACK pin)\n6) 4.19MHz crystal resonator can be used.\n7) 8-pin DIP package. (BU8874)Applications\;
