- **Data Rate:** Up to **20Mbps**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Number of Drivers/Receivers:** **1 Driver, 1 Receiver**  
- **Interface Type:** **RS-485, RS-422**  
- **Package:** **10-Lead µMAX (MSOP-10)**  
- **ESD Protection:** **±15kV (Human Body Model)**  
- **Quiescent Current (Supply):** **1.5mA (Typical)**  
- **Half-Duplex Operation**  

### **Descriptions:**
- The ISL3173EIUZ is designed for high-speed bidirectional data communication over balanced transmission lines.  
- It supports **RS-485 and RS-422** standards, making it suitable for industrial, automotive, and networking applications.  
- The device features **low-power operation** and **high noise immunity** in electrically noisy environments.  

### **Features:**
- **20Mbps Data Rate** for high-speed communication.  
- **3V to 5.5V Supply Range** for flexible power options.  
- **Enhanced ESD Protection (±15kV HBM)** for robustness.  
- **Low Power Consumption (1.5mA typical supply current).**  
- **Half-Duplex Operation** with driver/receiver enable controls.  
- **Thermal Shutdown Protection** to prevent damage from overheating.  
- **Short-Circuit Protection** on driver outputs.  
- **Compatible with 3.3V and 5V Logic Levels.**  

This transceiver is commonly used in **industrial automation, motor control, and networking equipment** due to its reliability and high-speed performance.  

(Note: INTERSIL was acquired by Renesas Electronics in 2017, but the original part number and specifications remain unchanged.)
