General Description
M-985-01 General 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 conditions. A power down (PD) feature is provided to further reduce power consumption when inactive.
M-985-01 Maximum Ratings
| Storage Temperature | -40 to 150 |
| Operating Ambient Temperature | -40 to 85 |
| VDD | 7V |
| Input Voltage on SIGIN | VSS - 6.5 to VDD + 0.3V |
| Input Voltages (except SIGIN) | VSS - 0.3 to VDD + 0.3 V |
| Lead Soldering Temperature | 260 for 5 seconds |
Note: Exceeding these ratings may permanently damage the M-985-01.
