Description and Introduction

Quad RS485 Line Receiver The LTC489CS is a quad differential line receiver manufactured by Linear Technology (now part of Analog Devices).  

### **Key Specifications:**  
- **Supply Voltage Range:** ±5V to ±12V  
- **Operating Temperature Range:** 0°C to 70°C (Commercial Grade)  
- **Package:** 16-Pin SOIC (CS suffix)  
- **Input Common-Mode Range:** ±25V  
- **Propagation Delay:** Typically 30ns  
- **CMRR (Common-Mode Rejection Ratio):** 70dB (min)  
- **Input Resistance:** 96kΩ (typical)  

### **Descriptions and Features:**  
- Designed for RS422/RS485 communication applications.  
- Quad differential receiver with high input impedance.  
- TTL-compatible outputs.  
- Fail-safe feature ensures a logic-high output when inputs are open or shorted.  
- Low power consumption.  
- High noise immunity due to differential signaling.  
- Suitable for long-distance data transmission.
