Description and Introduction

15kV ESD-Protected / Slew-Rate-Limited / Low-Power / RS-485/RS-422 Transceivers The MAX491EESD is a low-power, RS-422/RS-485 compliant transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MAX** (Maxim Integrated, now part of Analog Devices)  

### **Specifications:**  
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Data Rate:** Up to 2.5Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package Type:** 14-Pin SOIC (Small Outline Integrated Circuit)  
- **Low Power Consumption:**  
  - **Shutdown Current:** 1µA (max)  
  - **Supply Current (Active Mode):** 1.5mA (max)  
- **Half-Duplex Communication**  

### **Descriptions:**  
- The MAX491EESD is a low-power transceiver designed for RS-422 and RS-485 communication.  
- It features a single driver and receiver, making it suitable for half-duplex applications.  
- The device includes thermal shutdown protection to prevent damage from excessive power dissipation.  
- It is designed for balanced data transmission with high noise immunity in industrial environments.  

### **Features:**  
- **RS-422/RS-485 Compliant**  
- **Low-Power Shutdown Mode (1µA max)**  
- **Enhanced ESD Protection (±15kV HBM)**  
- **Driver Output Short-Circuit Protection**  
- **Thermal Shutdown Protection**  
- **Receiver Failsafe for Open/Shorted Inputs**  
- **Wide Common-Mode Voltage Range (-7V to +12V)**  
- **Controlled Driver Output Transition Times for Reduced EMI**
