TP3064BN

Overview

The TP3064BN is a full-duplex PCM codec manufactured by Texas Instruments, distributed by Rochester Electronics. It implements the MU-LAW companding algorithm for audio signal processing. The device operates in both synchronous and asynchronous modes and includes integrated filtering capabilities. It is housed in a 20-pin plastic DIP package with an inline rectangular form factor. Electrical specifications include a negative supply rating of -5 V and a commercial operating temperature range from 0 °C to 70 °C. The component is lead-free and utilizes tin-silver copper solder finish.

Feature Summary

• Supports full-duplex communication for simultaneous transmission and reception
• Integrates MU-LAW companding for standardized telephony audio compression
• Includes built-in filtering functions within the codec architecture

Applications

• Telecommunications equipment requiring PCM voice encoding and decoding
• Digital telephone systems utilizing standard MU-Law protocols
• Communication interfaces supporting synchronous or asynchronous data modes

Procurement Notes

Verify the manufacturer designation as Rochester Electronics, which acts as a commercial distributor for excess inventory rather than the original design entity. Confirm the specific package variant matches the PDIP-20 requirement. Ensure the MU-LAW functionality aligns with system standards. Check that the -5V negative supply rail compatibility fits the target circuit design constraints before finalizing acquisition.

Selection Notes

Select this component when a legacy telecommunications interface requires a dedicated hardware codec for MU-LAW processing. The choice depends on the availability of a through-hole DIP-20 package for prototyping or low-volume manufacturing. Verify that the single-function architecture meets the channel count requirements without necessitating additional multiplexing logic. Consider the commercial temperature grade sufficient for the intended operational environment.

Part Context

This part belongs to the family of PCM codecs designed for digital voice transmission. It serves as a specialized interface between analog audio signals and digital pulse code modulation networks. The device facilitates compliance with international telecommunication standards for voice digitization. Its role is critical in maintaining signal integrity during conversion processes in traditional telecom infrastructure.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate pin-compatible alternatives only if they explicitly support the same MU-LAW algorithm and -5V supply requirements. Verify functional equivalence regarding synchronous and asynchronous mode operations before considering any cross-reference.
