Low Power RS485 Transceiver with Receiver Fail-Safe The LTC1484CS8#PBF is a low-power RS485/RS422 transceiver manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage Range:** 3V to 5.5V  
- **Low Quiescent Current:** 300µA (typical)  
- **Half-Duplex Communication**  
- **Data Rate:** Up to 250kbps  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
The LTC1484CS8#PBF is designed for low-power RS485/RS422 applications. It features a low shutdown current and is suitable for battery-powered systems. The device includes fail-safe circuitry to ensure a high receiver output state when inputs are open or shorted.  

### **Features:**  
- **Low Power Consumption:** 300µA supply current (typical)  
- **Shutdown Mode:** Reduces current to 1µA (typical)  
- **Enhanced ESD Protection:** ±15kV on transceiver pins  
- **Thermal Shutdown Protection**  
- **Driver Output Short-Circuit Protection**  
- **Receiver Open-Circuit Fail-Safe**  

This transceiver is commonly used in industrial control, instrumentation, and communication systems.
