Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX491CSD is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX491CSD  
- **Package:** 14-SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage:** 4.5V to 5.5V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** 0°C to +70°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Shutdown Mode):** 1µA (typical)  
- **Supply Current (Active Mode):** 1mA (typical)  

### **Descriptions:**  
The MAX491CSD is a low-power RS-485/RS-422 transceiver designed for half-duplex communication. It features a driver and receiver with slew-rate limiting to reduce EMI and minimize reflections in improperly terminated cables. The device includes a low-power shutdown mode to conserve energy when not in use.  

### **Features:**  
- **Low Power Consumption:**  
  - 1µA shutdown current  
  - 1mA active supply current  
- **Slew-Rate Limited for Reduced EMI**  
- **Enhanced ESD Protection (±15kV HBM)**  
- **Half-Duplex Communication**  
- **Wide Supply Voltage Range (4.5V to 5.5V)**  
- **Thermal Shutdown Protection**  
- **Compatible with RS-485 and RS-422 Standards**  
- **Short-Circuit Current Limiting**
