Description and Introduction

TP3052, TP3053, TP3054, TP3057, Enhanced Serial Interface CODEC/Filter COMBO Family The part **TP3057V** is manufactured by **NS (National Semiconductor)**. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Type:** Telecom Interface IC  
- **Function:** PCM Codec-Filter  
- **Data Rate:** 64 kbps (PCM)  
- **Operating Voltage:** Typically ±5V  
- **Package:** 16-pin DIP (Dual In-line Package) or SOIC  
- **Operating Temperature Range:** Commercial (0°C to +70°C) or Industrial (-40°C to +85°C)  

### **Descriptions:**  
- The **TP3057V** is a **PCM (Pulse Code Modulation) codec-filter** designed for telecom applications.  
- It integrates both **encoding (A/D conversion)** and **decoding (D/A conversion)** functions for digital telephony systems.  
- Commonly used in **T1/E1 line cards, PBX systems, and digital telephony equipment**.  

### **Features:**  
- **On-chip filters** (anti-aliasing and reconstruction).  
- **μ-law/A-law companding** (selectable).  
- **Low power consumption** for telecom applications.  
- **Single +5V supply operation** (with external ±5V for analog sections).  
- **Compatible with TTL/CMOS logic levels**.  

For exact datasheet details, refer to the **National Semiconductor (NS) documentation**.

Application Scenarios & Design Considerations

TP3052, TP3053, TP3054, TP3057, Enhanced Serial Interface CODEC/Filter COMBO Family

Alternative Part Number

  • MC145480DW --: Pin-compatible PCM codec/filter in the same family as the TP3057, widely used as a direct substitute for National Semiconductor's TP305x series.
  • TP3054V --: Same TP305x codec family with identical pinout and function, differing only in companding law, making it a close functional replacement.
  • W6811 --: Modern single-channel PCM codec with similar functionality and interface, suitable as a replacement where the original TP3057 is unavailable.
  • MC145507P --: Pin-compatible codec/filter IC in the same telecom voice-band family, widely used as a direct substitute for TP3057V.
  • TP3057N --: Same device family in a DIP package, electrically equivalent and often interchangeable in through-hole designs.
  • MC145557P --: Similar voice-band codec/filter function with compatible pinout, suitable as a functional replacement.
