3V/5V General Purpose Call Progress Tone Detector Features - Covers the 315 to 640 Hz range (mon call progress) - Sensitivity to -38 d Bm - Dynamic range over 38 d B - 40 ms minimum detect - 8-pin DIP or 16-pin SOIC - Single supply CMOS (low power) - Supply range 2.8 to 5.5 VDC - Inexpensive 3.58 MHz time base - Low power consumption (<_15 m W at 3V) Applications - Automatic dialers - Dialing modems - Traffic measurement equipment - Test equipment - Service evaluation - Billing systems Pin Diagram Description 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 crystal-controlled time base guarantees accuracy and repeatability. 3V/5V operation increases customer flexibility, improves reliability, and minimizes power consumption.
