Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX485EESA is a low-power transceiver for RS-485 and RS-422 communication, manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 8-pin SOIC (MAX485EESA)  
- **Low Power Consumption:**  
  - **Shutdown Current:** 0.1µA (max)  
  - **Quiescent Current:** 300µA (max)  

### **Descriptions:**  
The MAX485EESA is designed for balanced data transmission and complies with RS-485 and RS-422 standards. It features a slew-rate-limited driver to minimize EMI and reduce reflections caused by improperly terminated cables.  

### **Features:**  
- **Low-Power Operation** for battery-powered applications  
- **Slew-Rate Limited Driver** for reduced EMI  
- **Thermal Shutdown Protection**  
- **Receiver Fail-Safe Design** (ensures logic-high output when inputs are open or shorted)  
- **Allows up to 32 Transceivers on the Bus**  
- **Wide Common-Mode Voltage Range:** -7V to +12V  

This transceiver is commonly used in industrial control systems, building automation, and point-to-point data transmission applications.
