MT8967AS1

Telecom Overview

The MT8967AS1 is a single-channel PCM CODEC manufactured by Microchip Technology, designed for telecommunications interface applications. It operates within a supply voltage range of 4.75V to 5.25V and draws a typical supply current of 3mA. The device supports an operating temperature range from 0°C to 70°C and is housed in a 20-SOIC package with a width of 7.50mm (0.295 inches). It utilizes a surface-mount installation type and features a PCM interface. The component is classified as obsolete status as of May 16, 2017, and complies with RoHS3 specifications.

Telecom Feature Summary

• Integrates PCM codec functionality for single-channel telecommunications signal processing
• Supports standard 5V logic operation with low power consumption characteristics
• Compatible with surface-mount assembly processes using a 20-pin SOIC footprint

Telecom Applications

• Digital telephone exchange systems
• PSTN interface circuits
• Telecommunications equipment requiring PCM encoding/decoding

Telecom Procurement Notes

Verify component obsolescence status prior to integration, as the MT8967AS1 was declared obsolete on May 16, 2017. Confirm availability through authorized distributors or surplus channels, noting that original manufacturer production has ceased. Ensure compliance with RoHS3 requirements if applicable to the target system. Validate pin compatibility and thermal performance against design specifications before finalizing procurement decisions.

Telecom Selection Notes

Select this component only if legacy support for single-channel PCM interfaces is required. Consider the 20-SOIC package constraints and 0°C to 70°C industrial temperature range limitations. Evaluate alternative modern codecs if new designs are initiated, given the discontinued status. Verify that the 3mA supply current and 5V operating voltage align with the system's power budget and logic levels.

Telecom Part Context

The MT8967AS1 belongs to Microchip's legacy telecommunications IC portfolio, specifically within the PCM CODEC category. It serves as a digital interface solution for converting analog voice signals to PCM digital data and vice versa. This part is often associated with older generation switching systems and network infrastructure where standardized PCM protocols are mandated.

Telecom Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct pin-to-pin replacements may require verification against specific application requirements. Consult Microchip technical support for potential recommended upgrades or compatible modern equivalents.
