### **Description:**  
The MAX490EESA is a low-power RS-485/RS-422 transceiver designed for half-duplex communication. It features slew-rate-limited drivers to minimize EMI and reduce reflections in improperly terminated cables. The device operates from a single +5V supply and includes a low-power shutdown mode.  

### **Features:**  
- Low-power RS-485/RS-422 transceiver  
- Slew-rate-limited for reduced EMI  
- Half-duplex operation  
- Single +5V supply operation  
- 1µA shutdown current (max)  
- Thermal shutdown protection  
- -7V to +12V common-mode input voltage range  
- Three-state outputs  
- ESD protection (±15kV)  

This device is commonly used in industrial control, telecommunications, and other applications requiring robust differential data transmission.
