The M-980-02 is an integrated circuit tone detector for general purpose use in automatic following of switched telephone calls. The circuit uses low-power CMOS techniques to provide the plete filtering and control required for this function. The basic timing of the M980-02 is designed to permit operation with almost any progress tone system. The use of integrated circuit techniques allows the M-980-02 to pack the plete frequency and amplitude portion of call progress following into a single 8pin DIP or 16-pin SOIC. A 3.58 MHz...
