M-980-02S

Telecom Overview

The M-980-02S is a communication integrated circuit designed as a call progress band tone detector. It operates within a supply voltage range of 2.8 V to 5.5 V and draws a typical operating current of 5 mA. The device supports a frequency of 3.58 MHz and functions reliably across an extended temperature range from -40°C to +85°C. Packaged in a 16-lead SOIC surface-mount format, this component was manufactured by IXYS Integrated Circuits. The product has reached its end-of-life stage and is no longer in active production.

Telecom Feature Summary

• Integrated detection capability for call progress band tones in communication systems
• Surface-mount design suitable for automated PCB assembly processes
• Operates on standard low-voltage power supplies common in portable devices

Telecom Applications

• Call progress tone detection in telecommunication equipment
• Voiceband signal processing in communication interfaces
• Legacy telephone system integration

Telecom Procurement Notes

This component is officially discontinued and marked as End-of-Life by the manufacturer. Current availability is limited to existing stock held by distributors or secondary market sources. Buyers should verify the authenticity and storage history of available units carefully. Design-in activities are not recommended due to the lack of future supply assurance and potential obsolescence risks associated with legacy components.

Telecom Selection Notes

Engineers replacing this part must evaluate functional compatibility with modern alternatives, as direct pin-for-pin substitutes may not exist. Considerations should include verifying that replacement ICs support the required 3.58 MHz frequency and operate within the same 2.8 V to 5.5 V voltage window. Package footprint changes may require PCB re-layout if alternative SOIC-16 variants differ in dimensions.
