### **Descriptions:**  
- The MAX490EESA+T is designed for half-duplex communication in RS-485/RS-422 networks.  
- It features slew-rate-limited drivers to reduce EMI and minimize reflections in unterminated cables.  
- Includes thermal shutdown protection to prevent damage from excessive power dissipation.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Slew-Rate Limited:** Reduces EMI and ensures signal integrity.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Half-Duplex Operation:** Supports bidirectional communication on a single twisted pair.  
- **Thermal Shutdown:** Prevents damage from short-circuit conditions.  

This transceiver is commonly used in industrial control, automotive, and instrumentation applications.
