Description and Introduction

Meter-Bus Transceiver 16-SOIC The TSS721A is a transceiver interface IC manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage (VDD):** 3.3V to 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Communication Protocol:** Supports M-Bus (Meter-Bus) standard EN 1434-3  
- **Data Rate:** Up to 9600 baud  
- **Interface:** Half-duplex  

### **Description:**  
The TSS721A is a monolithic IC designed for interfacing between a microcontroller and an M-Bus (Meter-Bus) network. It provides the necessary voltage regulation and signal conditioning for bidirectional communication in energy metering applications.  

### **Features:**  
- Integrated voltage regulator for M-Bus slave devices  
- Low power consumption in standby mode  
- Reverse polarity protection  
- Short-circuit protection on the bus side  
- Compatible with standard UART interfaces  

For further details, refer to the official Texas Instruments datasheet.

Application Scenarios & Design Considerations

Meter-Bus Transceiver 16-SOIC

Alternative Part Number

  • M-BUS-1 --: M-Bus transceiver IC that provides a similar meter bus interface function to the TSS721A, suitable as a functional replacement in M-Bus slave applications.
  • MAX14830 --: Multi-channel UART transceiver that can be configured for meter bus communication, offering a flexible alternative when the TSS721A is unavailable.
  • ST7540 --: Power line transceiver IC used in metering and M-Bus-like communication systems, providing a comparable interface solution with a different series name.
