M-985-01
Precise Call Progress and
Special Information Tone Generator
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 combines 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 con-
ditions. A power down (PD) feature is provided to fur-
ther reduce power consumption when inactive.

Note:
Exceeding these ratings may permanently damage the M-985-01.
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.
