Description and Introduction

Low-Power / Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX483CSA 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:

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

### **Specifications:**  
- **Part Number:** MAX483CSA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Interface Type:** RS-422/RS-485  
- **Data Rate:** Up to 250kbps  
- **Supply Voltage:** 4.75V to 5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Low Power Consumption:**  
  - **Supply Current (Shutdown):** 0.1µA (typical)  
  - **Supply Current (Unloaded):** 120µA (typical)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Half-Duplex Operation**  

### **Descriptions:**  
- The MAX483CSA is a low-power RS-485/RS-422 transceiver designed for balanced communication.  
- It features reduced slew-rate drivers to minimize EMI and reflections, making it suitable for electrically noisy environments.  
- The device includes a receiver with fail-safe circuitry, ensuring a logic-high output when inputs are open or shorted.  
- It is commonly used in industrial control systems, building automation, and other applications requiring robust serial communication.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **Slew-Rate Limited Drivers:** Reduces EMI and signal reflections.  
- **Receiver Fail-Safe:** Ensures valid output with open or shorted inputs.  
- **ESD Protection:** Protects against electrostatic discharge.  
- **Half-Duplex Communication:** Supports bidirectional data transfer on a single pair.  
- **Wide Supply Range:** Operates from 4.75V to 5.25V.  

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