Product Information

M-982-02 Precise Call Progress Tone Detector Features • Precise detection of call progress tones • Linear (analog) input • Digital (CMOS compatible), tri-state outputs • 22-pin DIP and 20-pin SOIC • Single supply 3 to 5 volt (low power CMOS) • Inexpensive 3.58 MHz crystal time base • Wide dynamic range (30 dB) • Lower power consumption (power-down mode) • 425 Hz detection Description The M-982-02 is an integrated circuit precise tone detector for special-purpose use in automatic following of switched telephone calls. The circuit uses lowpower CMOS techniques to provide the complete filtering and control required for this function. The basic timing of the M-982-02 is designed to permit operation with almost any progress tone system.The use of integrated circuit techniques allows the M-982-02 to pack the five filters for call progress following into a single 22-pin DIP or 20-pin SOIC. A 3.58 MHz crystal-controlled time base guarantees accuracy and repeatability. The M-982-02 is an enhanced drop-in replacement for the M-982-01. It has a wider operating voltage range (down to 3V). It has lower power consumption under normal operating conditions. In addition, a powerdown (PD) feature is provided to further reduce power consumption when inactive. It includes a 425 Hz detector to support common international call progress requirement. Applications • Automatic dialers • Dialing modems • Traffic • Measurement equipment • Test equipment • Service evaluation • Billing systems Pin Diagram Ordering Information Part # Description M-982-02P M-982-02S M-982-02T 22-pin plastic DIP 20-pin plastic SOIC 20-pin plastic SOIC,Tape and Reel Block Diagram DS-M982-02-R4 www.clare.com 1 M-982-02 Absolute Maximum Ratings Storage Temperature Operating Ambient Temperature VDD Input Voltage on SIGIN Input Voltages (except SIGIN) Lead Soldering Temperature -40 to 150°C -40 to 85°C 7V VSS - 6.5 to VDD + 0.3V VSS - 0.3 to VDD + 0.3 V 260° C for 5 seconds 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 device to the absolute maximum ratings for an extended period may degrade the device and effect its reliability. Note: Exceeding these ratings may permanently damage the M-982-02.
