±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX490EEPA+ is a low-power, slew-rate-limited RS-485/RS-422 transceiver 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  
- **Slew Rate Limited:** Reduces EMI and reflections  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1µA (max)  
  - **Operating Current:** 120µA (max)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 8-Pin PDIP  

### **Descriptions:**  
- Designed for **half-duplex** RS-485/RS-422 communication.  
- Features **slew-rate-limited** drivers to minimize EMI and reduce reflections in unterminated cables.  
- Includes **thermal shutdown** and **short-circuit protection**.  
- Supports **fail-safe receiver operation** (ensures a logic-high output when inputs are open or shorted).  

### **Features:**  
- Low-power operation for battery-powered applications.  
- Slew-rate limiting for reduced EMI.  
- Enhanced ESD protection (±15kV HBM).  
- Thermal shutdown and driver short-circuit protection.  
- Compatible with RS-485 and RS-422 standards.  

This transceiver is commonly used in industrial control, automotive, and instrumentation applications requiring robust serial communication.
