MC145503P

Codecs Overview

The MC145503P is a high-performance audio codec manufactured by Motorola, now under NXP. It is a PCM codec-filter mono-circuit designed for single-supply operation. The device integrates A-law and μ-law encoding/decoding functions within a single functional block. It utilizes a 16-PDIP plastic package. The component supports standard PCM interface protocols and includes internal filtering capabilities to process audio signals efficiently in communication systems requiring digital voice transmission.

Codecs Feature Summary

• Integrates PCM codec and filter functions into a single mono-circuit
• Supports both A-law and μ-law encoding and decoding standards
• Designed for single-supply voltage operation
• Provides high-performance audio processing capabilities

Codecs Applications

• Digital voice transmission systems
• Communication equipment requiring PCM interfacing
• Audio processing circuits with A-law or μ-law requirements

Codecs Procurement Notes

Verify the manufacturer source carefully, as production has transitioned from Motorola to NXP and Rochester Electronics. Confirm the specific datasheet version matches the required A/MU-law functionality. Ensure the PDIP-16 package type aligns with your board design constraints. Check for any obsolescence notices or lifecycle status updates from authorized distributors before placing orders.

Codecs Selection Notes

Select this component when a single-chip solution for PCM audio coding is required. It is suitable for applications needing both encoding and decoding without external logic. Consider the single-supply advantage for power-sensitive designs. Verify compatibility with existing PCM bus architectures and timing requirements for seamless integration into legacy or new communication hardware.

Codecs Part Context
