TELTONE - M980 - CALL PROCESS TONE DECODER, Dip8, New
The Teltone® M-980 is an integrated circuit tone detector for general purpose use in automatic following of switched telephone calls. The circuit uses low-power CMOS techniques to provide the complete filtering and control required for this function. The basic timing of the M-980 is designed to permit operation with almost any progress tone system. The use of integrated circuit techniques allows the M-980 to pack the complete frequency and amplitude portion of call progress following into a single 8-pin DIP. A 3.58 MHz crystal-controlled time base guarantees accuracy and repeatability
Features • Covers the 315 to 640 Hz range (common call progress) • Sensitivity to -38 dBm • Dynamic range over 36 dB • 40 ms minimum detect (50 ms to output) • 8-pin DIP or 16-pin SOIC • Single supply CMOS (low power) • Supply range 4.5 to 5.5 VDC • Inexpensive 3.58-MHz time base
CALL PROCESS TONE DECODER - Great for Telephone redial systems, Dialing modems, Telecom applications New 8-Dip.
Applications: Automatic dialers, Dialing modems, Traffic measurement equipment, Test equipment, Service evaluation, Billing systems
