### **Descriptions:**  
The LTC1485IS8#PBF is a low-power differential bus transceiver designed for RS485/RS422 communication. It features a high-impedance receiver input and a driver with short-circuit current limiting. The device operates from a single 3V to 5.5V supply and includes thermal shutdown protection.  

### **Features:**  
- **Half-Duplex Operation**  
- **Low Power Consumption**  
- **Enhanced ESD Protection**  
- **Thermal Shutdown Protection**  
- **Short-Circuit Current Limiting**  
- **High Input Impedance (≥96kΩ)**  
- **Compatible with TIA/EIA-485-A Standards**  

This transceiver is suitable for industrial, automotive, and communication applications requiring robust and low-power RS485/RS422 interfaces.
