Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX483ESA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX483ESA  
- **Type:** RS-485/RS-422 Transceiver  
- **Supply Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Current Consumption (Quiescent):** 120µA (typical)  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**  
The MAX483ESA is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features reduced EMI and reflections due to its controlled slew rate, making it suitable for noise-sensitive applications. The device operates from a single 5V supply and includes a driver and receiver for half-duplex communication.  

### **Features:**  
- Low-power operation (120µA quiescent current)  
- Slew-rate-limited for reduced EMI  
- Half-duplex communication  
- Thermal shutdown protection  
- Short-circuit current limiting  
- -7V to +12V common-mode input voltage range  
- Three-state outputs  
- Compatible with RS-485 and RS-422 standards  

This transceiver is commonly used in industrial control systems, instrumentation, and long-distance communication networks.

Application Scenarios & Design Considerations

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers

Alternative Part Number

  • SN75176BDR --: Industry-standard RS-485/RS-422 transceiver, pin-compatible with MAX483 in SOIC-8, widely available and cost-effective.
  • SP483ECN-L --: Direct functional equivalent RS-485 transceiver with low-power shutdown, same 8-pin package and pinout as MAX483.
  • ST485ECDR --: RS-485/RS-422 transceiver with similar slew-rate-limited driver and low power consumption, suitable drop-in replacement in most designs.
