Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX481MJA is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Operating Temperature Range:** -55°C to +125°C (military-grade, indicated by "MJ" suffix)  
- **Data Rate:** Up to 2.5Mbps  
- **Quiescent Current:** 120µA (typical) in shutdown mode  
- **Driver Output Current:** ±60mA (short-circuit protected)  
- **Receiver Input Sensitivity:** ±200mV  
- **Receiver Input Resistance:** 12kΩ (minimum)  
- **Package:** 8-pin CERDIP (J-lead, military-grade)  

### **Descriptions:**  
- The MAX481MJA is a low-power RS-485/RS-422 compliant transceiver designed for half-duplex communication.  
- It is part of Maxim's ruggedized product line, suitable for harsh environments due to its military-grade temperature range.  
- Includes a slew-rate-limited driver to reduce EMI and minimize reflections in improperly terminated cables.  

### **Features:**  
- **Low Power Consumption:** Operates at 120µA in shutdown mode.  
- **ESD Protection:** ±15kV (Human Body Model) on driver outputs and receiver inputs.  
- **Thermal Shutdown Protection:** Prevents damage during fault conditions.  
- **Slew-Rate Limited Driver:** Reduces EMI and ensures signal integrity.  
- **Half-Duplex Communication:** Supports bidirectional data transmission on a single twisted-pair line.  
- **Wide Common-Mode Range:** -7V to +12V for robust noise immunity in industrial environments.  

The MAX481MJA is commonly used in industrial control systems, automotive applications, and military communications where reliability and extended temperature operation are critical.  

(Note: Always verify datasheet details for exact specifications before design implementation.)
