Description and Introduction

15kV ESD Protected/ 20Mbps/ 5V/ Low Power/ RS-485/RS-422 Transceiver The ISL4485EIB is a RS-485/RS-422 transceiver manufactured by Intersil (now part of Renesas Electronics). Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Supply Voltage:** 4.5V to 5.5V  
- **Data Rate:** Up to 16Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC (Small Outline Integrated Circuit)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Bus I/O Protection:** ±12V (RS-485 Input Levels)  
- **Low Power Consumption:** 1.5mA (Typical Supply Current)  

### **Description:**  
The ISL4485EIB is a high-speed, low-power RS-485/RS-422 transceiver designed for balanced communication over long distances. It supports half-duplex communication and features enhanced ESD protection, making it suitable for industrial and automotive applications.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 16Mbps.  
- **Low Power Consumption:** Ideal for power-sensitive applications.  
- **Enhanced ESD Protection:** ±15kV HBM on bus pins.  
- **Wide Common-Mode Range:** ±12V for robust noise immunity.  
- **Short-Circuit Protection:** Driver outputs protected against faults.  
- **Thermal Shutdown:** Prevents damage from overheating.  
- **Half-Duplex Operation:** Single differential bus for bidirectional communication.  
- **3-State Driver Outputs:** Allows bus sharing in multi-drop networks.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
