M-985-01S Datasheet | Clare

Features - - - - - - - - - - Precise detection of call progress tones Linear (analog) input Digital (CMOS patible), 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 d B) Lower power consumption (power-down mode) 425 Hz detection Special Information Tone (SIT) Detection Description The M-985-01 is an integrated circuit precise tone detector for call progress and special information tones (SIT), as defined by CCITT. The use of integrated circuit techniques allows the M-985-01 to pack the eight filters for call progress detection into a single 22-pin DIP or a 20-pin SOIC. A 3.58 MHz crystal-controlled time base guarantees accuracy and repeatability. The M-985-01 bines the call progress detection of the M-982-02 and the SIT detection of the M-984-02. It has an operating voltage range down to 3V. It has low power consumption under normal operating conditions. A power down (PD) feature is provided to further reduce power consumption when inactive.
