M-980-02S Datasheet | Clare

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.

M-980-02 Absolute Maximum Ratings DC Supply Voltage (VDD - VSS) 6.0V Voltage on SIGNAL IN(VDD+ 0.5V) to (VSS-12V) Voltage on Any Pin Except SIGNAL IN (VDD + 0.5V) to VSS -0.5V Storage Temperature Range -65° to 150°C Operating Temperature -40°C to 85°C Lead Soldering Temperature 260° for 5 seconds Note: Exceeding these ratings may permanently damage the M-980-02. Absolute Maximum Ratings are stress ratings. Stresses in excess of these ratings can cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this data sheet is not implied. Exposure of the...
