Description and Introduction

±15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX491ESD+ is a low-power transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** RS-422/RS-485 Transceiver  
- **Operating Voltage:** 4.75V to 5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-14  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Supply Current (Quiescent):** 120µA (Typical)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Common-Mode Input Voltage Range:** -7V to +12V  

### **Descriptions:**  
The MAX491ESD+ is a low-power, high-speed 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 operates from a single 5V supply and includes thermal shutdown protection to prevent damage from excessive power dissipation.  

### **Features:**  
- Low power consumption (120µA quiescent current)  
- High-speed data transmission (up to 2.5Mbps)  
- ESD protection (±15kV HBM)  
- Thermal shutdown protection  
- Half-duplex communication  
- Wide common-mode input voltage range (-7V to +12V)  
- Operates from a single 5V supply  
- SOIC-14 package for compact PCB design
