Description and Introduction

7 V, parallel interface CODEC/filter COMBO The part TP3056J is manufactured by National Semiconductor (NS). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** National Semiconductor (NS)  
- **Part Number:** TP3056J  
- **Type:** Telecom Interface IC  
- **Function:** PCM Codec-Filter (Pulse Code Modulation)  
- **Operating Voltage:** Typically ±5V  
- **Package:** Plastic DIP (Dual In-line Package)  
- **Pin Count:** 16 pins  
- **Data Rate:** Supports standard PCM data rates (e.g., 64 kbps)  
- **Compliance:** Meets telecom standards for voice encoding/decoding  

### **Descriptions:**  
The TP3056J is a PCM codec-filter IC designed for telecommunications applications. It integrates both an encoder (A/D converter) and a decoder (D/A converter) with a band-limiting filter, making it suitable for voice signal processing in digital telephony systems.  

### **Features:**  
- **Integrated PCM Codec:** Combines analog-to-digital (A/D) and digital-to-analog (D/A) conversion.  
- **On-Chip Filtering:** Includes transmit and receive filters for band-limiting signals.  
- **Low Power Consumption:** Designed for efficient operation in telecom equipment.  
- **Wide Operating Voltage Range:** Compatible with standard telecom power supplies.  
- **Industry-Standard Pinout:** Facilitates easy integration into existing designs.  

This information is strictly based on the available knowledge base. No additional guidance or suggestions are provided.

Application Scenarios & Design Considerations

7 V, parallel interface CODEC/filter COMBO

Alternative Part Number

  • MC145506P --: Pin-compatible PCM codec/filter in the same family as the TP3056, widely available as a second source.
  • TP3057N --: Same TP305x codec family with matching pinout and function, differing only in naming suffix.
  • W6811 --: Modern single-channel PCM codec offering comparable functionality and a different naming series for easy distinction.
  • TP3054J --: Same TP305x codec-filter series with nearly identical electrical characteristics, differing mainly in companding option, so it is a close functional drop-in.
  • MC145502P --: Comparable mu-law PCM codec-filter with matching pinout and supply requirements, suitable as a second-source alternative.
