Special Information Tone Detector
Description
The M-984-02 Special Information Tone Detector is a
monolithic integrated circuit designed to provide reli-
able detection of many common telephone network
status signals. In particular, it detects the signals
known as Special Information Tones (SITs) or error
tones as defined by the CCITT, and single tones often
used as dial tone, audible ringing, and other general
progress indications. The M-984-02 uses CMOS
switched capacitor filters and a crystal time base to
achieve the high stability and accuracy specified. Each
tone detection window has an associated output pin,
which can be placed in a high impedance state for use
with time-share microcomputer bus applications.
In comparison with the earlier M-984, the M-984-02
has wider acceptance bands for SIT tones to facilitate
reception of tape-loop tones, lower power consump-
tion at 5V operation, 3V operation, superior tempera-
ture performance, lower cost, and is available in DIP,
SOIC, and SOIC tape and reel versions.

Note:
Exceeding these ratings may permanently damage the device.
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.
