### **Specifications:**
- **Supply Voltage:** 3.3V ±10%  
- **Data Rate:** Up to 12Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low-Power Shutdown Mode:** 1µA (max)  
- **Package:** 8-pin SOIC  

### **Descriptions:**
- The MAX3485ECSA is designed for balanced data transmission in RS-485/RS-422 applications.  
- It features slew-rate-limited drivers to reduce EMI and minimize reflections in improperly terminated networks.  
- The device includes a fail-safe circuit ensuring a logic-high receiver output when inputs are open or shorted.  
- It is suitable for industrial control, telecom, and networking applications.  

### **Features:**
- **3.3V Operation** – Compatible with low-voltage systems.  
- **Slew-Rate Limited** – Reduces EMI and signal reflections.  
- **Half-Duplex Operation** – Allows bidirectional communication on a single pair.  
- **Low-Power Shutdown Mode** – Consumes minimal current when disabled.  
- **Thermal Shutdown Protection** – Prevents damage from excessive power dissipation.  
- **Enhanced ESD Protection** – ±15kV protection on driver outputs and receiver inputs.
