Description and Introduction

±15kV ESD-Protected, Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX3085EESA is a ±15kV ESD-protected, 20Mbps, slew-rate-limited, RS-485/RS-422 transceiver manufactured by Maxim Integrated.  

### **Specifications:**  
- **Data Rate:** Up to 20Mbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Voltage Range:** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin SOIC (MAX3085EESA)  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half/Full Duplex:** Half-Duplex  
- **Slew-Rate Limited:** Yes (for reduced EMI)  
- **Common-Mode Input Voltage Range:** ±12V  
- **Receiver Input Resistance:** ≥12kΩ  

### **Descriptions:**  
The MAX3085EESA is designed for high-speed RS-485/RS-422 communication with enhanced ESD protection. It features slew-rate limiting to minimize EMI and ensure signal integrity in noisy environments. The device operates from a single 5V supply and is suitable for industrial, automotive, and telecom applications.  

### **Features:**  
- ±15kV ESD protection on bus pins  
- Slew-rate-limited for low EMI  
- 20Mbps data rate  
- Half-duplex operation  
- Low-power shutdown mode (1μA typical)  
- Thermal shutdown protection  
- Short-circuit current limiting  
- Compatible with RS-485 and RS-422 standards  

This transceiver is ideal for applications requiring robust communication over long distances in electrically harsh environments.
