M-982-02
Precise Call Progress Tone Detector
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 low-
power CMOS techniques to provide the complete fil-
tering 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 inte-
grated 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-con-
trolled time base guarantees accuracy and repeatabil-
ity.
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 power-
down (PD) feature is provided to further reduce power
consumption when inactive. It includes a 425 Hz
detector to support common international call progress
requirement.

Note: Exceeding these ratings may permanently damage the M-982-02.
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.
