MT8961AE1

Telecom Overview

The MT8961AE1 is a single-channel PCM CODEC integrated circuit manufactured by Microchip Technology. Designed for telecommunications applications, it facilitates analog-to-digital and digital-to-analog conversion within voice communication systems. The device operates on a single 5V supply voltage with a range of 4.75V to 5.25V and draws a typical supply current of 3mA. It is housed in an 18-pin Plastic Dual In-Line Package (PDIP) with a 0.300-inch (7.62mm) width, suitable for through-hole mounting. The component supports standard PCM interfaces and functions within an operating temperature range of 0°C to 70°C.

Telecom Feature Summary

• Integrates PCM codec functionality for single-channel voice signal processing
• Supports standard PCM interface protocols for telecommunications equipment
• Operates on a standard 5V power supply with low current consumption

Telecom Applications

• Public switched telephone network (PSTN) terminal equipment
• Digital telephony switching systems
• Voice communication interface modules

Telecom Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified secondary market suppliers due to the part's discontinued status. Request original manufacturer documentation or traceability records to confirm the component has not been refurbished or counterfeited. Ensure the package matches the specified 18-PDIP form factor and inspect leads for integrity before integration into designs requiring legacy support.

Telecom Selection Notes

Select this component only when a specific legacy PCM codec interface is required for existing hardware architectures. Consider the 18-PDIP package constraints and through-hole mounting requirements during PCB layout. Evaluate the 0°C to 70°C commercial temperature range against environmental conditions. Assess availability challenges associated with end-of-life status and potential long-term supply risks for maintenance projects.

Telecom Part Context

The MT8961AE1 belongs to Microchip's legacy telecommunications IC portfolio, specifically designed for PCM codec applications. It represents a specialized solution for voice channel processing in traditional telecom infrastructure. As a discontinued product, it serves primarily in maintenance, repair, and overhaul (MRO) contexts for established communication systems rather than new design implementations.

Telecom Replacement Considerations

No public confirmed substitute part numbers are available for direct replacement.
