Description and Introduction

20µA, 1/8-Unit Load, Slew-Rate Limited, RS-485 Transceivers The MAX1482 is a complete, electrically isolated RS-485/RS-422 data interface manufactured by Maxim Integrated. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Data Rate:** Up to 2.5Mbps  
- **Supply Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Isolation Voltage:** 2500Vrms (1 minute)  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Propagation Delay:** 40ns (typical)  
- **Common-Mode Voltage Range (Receiver):** ±25V  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Description:**  
The MAX1482 is a galvanically isolated RS-485/RS-422 transceiver that combines a high-speed optocoupler, a transformer driver, and a fully differential RS-485/RS-422 transceiver. It provides complete isolation for signal and power lines, making it suitable for industrial and harsh environments where ground loops and high-voltage transients are a concern.

### **Features:**  
- **Full Electrical Isolation:** Includes isolated power and data lines.  
- **High-Speed Operation:** Supports data rates up to 2.5Mbps.  
- **Low Power Consumption:** Typically 5mA supply current.  
- **Fail-Safe Receiver:** Ensures logic-high output when inputs are open or shorted.  
- **Short-Circuit Protection:** Driver outputs protected against short circuits.  
- **Wide Common-Mode Range:** Allows operation in noisy environments.  
- **Compact Package:** Available in 28-pin DIP and SO packages.  

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