Description and Introduction

+3.3V / 15kV ESD-Protected / Fail-Safe / Hot-Swap / RS-485/RS-422 Transceivers The MAX3073EESD is a 3.3V, ±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  
- **Data Rate:** Up to 20Mbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Half-Duplex Communication**  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Common-Mode Input Voltage Range:** ±12V  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1μA (max)  
  - **Supply Current (Unloaded):** 1.5mA (max)  

### **Features:**  
- **Enhanced ESD Protection:** Protects against ±15kV ESD strikes on bus pins.  
- **Failsafe Receiver:** Ensures logic-high output when inputs are open, shorted, or terminated but not driven.  
- **Hot-Swap Inputs:** Prevents false transitions during power-up.  
- **Slew-Rate Limited (MAX3073E):** Reduces EMI and reflections for improved signal integrity.  
- **Short-Circuit Protection:** Driver outputs are protected against short circuits.  
- **Industry-Standard Pinout:** Compatible with other RS-485 transceivers.  

### **Applications:**  
- Industrial automation  
- Building control systems  
- HVAC systems  
- RS-485/RS-422 networks  

### **Package:**  
- **14-Pin SOIC (MAX3073EESD)**  

This device is designed for robust communication in electrically noisy environments while maintaining high-speed performance.
