MAX3085EESA

±15kV ESD-Protected, Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3085EESA is a 3.3V-powered, ±15kV ESD-protected, 20Mbps, half-duplex RS-485/RS-422 transceiver manufactured by Maxim Integrated (now part of Analog Devices).  

### **Key Specifications:**  
- **Supply Voltage:** 3.3V ±10%  
- **Data Rate:** Up to 20Mbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MAX3085EESA)  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1µA (max)  
  - **Quiescent Current:** 900µA (max)  

### **Features:**  
- **Enhanced ESD Protection:** Protects against ±15kV on bus pins (IEC 61000-4-2 Air-Gap Discharge).  
- **Fail-Safe Receiver:** Ensures logic-high output when inputs are open, shorted, or terminated but not driven.  
- **Hot-Swap Input Structure:** Eliminates false transitions during power-up/down.  
- **Slew-Rate Limited for Reduced EMI (MAX3085EESA+ only)**  
- **Compatible with RS-485 and RS-422 Standards**  
- **Short-Circuit Protection on Driver Outputs**  
- **Thermal Shutdown Protection**  

### **Applications:**  
- Industrial control systems  
- Building automation  
- HVAC systems  
- Network equipment  
- Point-of-sale terminals  

This transceiver is designed for robust communication in noisy environments while maintaining low power consumption.
