Description and Introduction

Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX489CSD+T is a low-power transceiver manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX489CSD+T  
- **Package:** SOIC-14  
- **Operating Voltage:** +4.5V to +5.5V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Operating Temperature Range:** -40°C to +85°C  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Supply Current (Quiescent):** 120µA (Typical)  
- **Common-Mode Voltage Range:** ±7V  
- **Receiver Input Resistance:** ≥12kΩ  

### **Descriptions:**
- The MAX489CSD+T is a low-power, RS-485/RS-422 compliant transceiver designed for half-duplex communication.  
- It features a reduced slew-rate driver to minimize EMI and reduce reflections in unterminated cables.  
- The device includes fail-safe circuitry, ensuring a logic-high receiver output when inputs are open or shorted.  

### **Features:**
- **Low Power Consumption:** Operates at 120µA (typical) in shutdown mode.  
- **Enhanced ESD Protection:** ±15kV protection on driver outputs and receiver inputs.  
- **Half-Duplex Communication:** Supports bidirectional data transmission.  
- **Slew-Rate Limited Driver:** Reduces EMI and signal reflections.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Wide Common-Mode Range:** Allows ±7V tolerance for noise immunity in industrial environments.  
- **Compliant with RS-485/RS-422 Standards:** Ensures compatibility with industry protocols.  

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