  - **Supply Current (Unloaded):** 120µA (typical)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 8-Pin PDIP  

### **Descriptions:**  
- The MAX481EPA is a low-power, slew-rate-limited transceiver for RS-485/RS-422 communication.  
- It features a driver with short-circuit current limiting and thermal shutdown for enhanced protection.  
- The receiver includes a fail-safe feature that ensures a logic-high output when inputs are open or shorted.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Slew-Rate Limited:** Reduces EMI and reflections in unterminated cables.  
- **Driver Short-Circuit Protection:** Prevents damage during fault conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Wide Common-Mode Voltage Range:** -7V to +12V for robust noise immunity.  
- **Compatible with RS-485 and RS-422 Standards.**  

This information is strictly based on the manufacturer's datasheet.
