M-991 - Call Progress Tone Generator

Datasheet Summary

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.

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).
