### **Description:**  
The MAX1487EESA is a low-power, half-duplex RS-485/RS-422 transceiver designed for high-speed communication in electrically noisy environments. It features a single driver and receiver, making it suitable for bidirectional data transmission over balanced lines.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 2.5Mbps.  
- **Low Power Consumption:** Typically draws 120µA in shutdown mode.  
- **Enhanced ESD Protection:** ±15kV protection on driver outputs and receiver inputs.  
- **Wide Common-Mode Range:** Allows ±7V tolerance for noise immunity.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Driver Short-Circuit Current Limiting:** Protects against output shorts.  
- **Receiver Fail-Safe:** Ensures a logic-high output when inputs are open or shorted.  

This information is strictly based on the manufacturer's datasheet and specifications.
