±16.5kV ESD (IEC61000-4-2) Protected, Large Output Swing, 5V, Full Fail-Safe, 1/8 Unit Load, RS-485/RS-422 Transceivers The ISL3158EIBZ is a high-speed, half-duplex RS-485/RS-422 transceiver manufactured by **INTERSIL** (now part of Renesas Electronics). Below are the key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Supply Voltage:** 3.3V  
- **Data Rate:** Up to **40Mbps**  
- **Operating Temperature Range:** **-40°C to +85°C**  
- **Number of Drivers/Receivers:** **1 Driver, 1 Receiver**  
- **Protocol Support:** **RS-485, RS-422**  
- **Half-Duplex Operation**  
- **ESD Protection:** **±16kV (Human Body Model)**  
- **Package:** **8-SOIC**  

### **Descriptions:**
- Designed for **high-speed communication** in industrial and networking applications.  
- Supports **fail-safe receiver operation** (ensures logic-high output when inputs are open or shorted).  
- **Low-power shutdown mode** (consumes <1µA).  
- **3.3V operation** makes it suitable for low-voltage systems.  

### **Features:**
- **40Mbps data rate** for high-speed applications.  
- **Enhanced ESD protection** (±16kV HBM).  
- **Wide common-mode voltage range** (±12V) for noise immunity.  
- **Hot-swappable** (driver outputs remain in high-impedance during power-up/down).  
- **Short-circuit current limiting** and **thermal shutdown** for protection.  

This transceiver is commonly used in **industrial automation, motor control, and networking equipment**.  

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