Description
Ordering Information
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.
