### **Descriptions:**  
The LTC491CS#TR is a half-duplex RS485/RS422 transceiver designed for low-power applications. It features a slew-rate-limited driver to minimize EMI and reduce reflections in unterminated networks. The device includes a fail-safe receiver that ensures a logic-high output when inputs are open, shorted, or terminated but not driven.  

### **Features:**  
- Low power consumption  
- Slew-rate-limited driver for reduced EMI  
- Enhanced ESD protection (±10kV)  
- Half-duplex operation  
- Shutdown mode for power savings  
- Fail-safe receiver design  
- Operates with a single 5V supply  

This transceiver is suitable for industrial control, instrumentation, and multipoint data transmission systems.
