Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX487EESA is a low-power transceiver for RS-485 and RS-422 communication, manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 8-SOIC (150mil)  
- **Operating Voltage:** 4.75V to 5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current:** 120µA (Quiescent)  
- **Half-Duplex Operation**  
- **Slew Rate Limited for Reduced EMI**  
- **Common-Mode Input Voltage Range:** -7V to +12V  

### **Descriptions:**  
The MAX487EESA is designed for balanced data transmission and complies with RS-485 and RS-422 standards. It features low power consumption, making it suitable for battery-powered applications. The device includes slew-rate-limited drivers to minimize EMI and reduce reflections in improperly terminated cables.  

### **Features:**  
- Low Power Consumption (120µA Quiescent Current)  
- Slew-Rate Limited for Error-Free Data Transmission  
- Half-Duplex Communication  
- Extended Common-Mode Range (-7V to +12V)  
- ESD Protection (±15kV)  
- Thermal Shutdown Protection  
- Operates with a Single 5V Supply  

This transceiver is commonly used in industrial control systems, building automation, and other applications requiring robust serial communication.
