M-991
Call Progress Tone Generator
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 M-
991 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.

Operating Ambient Temperature
for the M-991-02SM
-40° to 85° C
VDD 7.0V
Any Input Voltage
VSS -0.6 to VDD +0.6V
Note:
1. Exceeding these ratings may permanently damage the M-991.
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 opera-
tional sections of this data sheet is not implied. Exposure of
the device to the absolute maximum ratings for an extend-
ed period may degrade the device and effect its reliability.
