M-991 Call Progress Tone Generator Features Generates standard call progress tones Digital input control Linear (analog) output Power output capable of driving standard line 14-pin DIP and 16-pin SOIC package types Single supply 5V CMOS (low power) Inexpensive 3.58 MHz time base Temperature range from -25ºC to 70ºC (-01 version) Temperature range from -40ºC to 85ºC (-02 version) Applications Telephone systems Test equipment Callback Security systems Billing systems Description The M-991 is a call progress tone generator integrated circuit for use in telephone systems. The circuit uses low-power CMOS techniques to generate tones which are digitally controlled and highly linear. The M-991 is designed to permit operation with almost any system. The use of integrated circuit techniques allows the M991 to incorporate the control, tone generating, and power output buffer into a single 14-pin DIP or a 16-pin SOIC. A 3.58-MHz (color burst) crystal-controlled time base guarantees accuracy and repeatability.
