Description and Introduction

20µA, 1/8-Unit-Load, Slew-Rate-Limited, RS-485 Transceivers The MAX1482CSD+ is a high-speed, low-power RS-485/RS-422 transceiver manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX1482CSD+  
- **Package:** 14-SOIC (150mil)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Common-Mode Voltage Range (Receiver):** -7V to +12V  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current (Shutdown Mode):** 1µA (max)  
- **Output Current (Driver):** ±60mA  

### **Descriptions:**  
The MAX1482CSD+ is a low-power, high-speed RS-485/RS-422 transceiver designed for balanced data transmission. It features a slew-rate-limited driver to reduce EMI and ensure error-free data transmission at high speeds. The device includes a fail-safe receiver that ensures a logic-high output when inputs are open, shorted, or terminated but not driven.

### **Features:**  
- **Low Power Consumption:**  
  - 120µA (max) supply current in active mode  
  - 1µA (max) in shutdown mode  
- **High-Speed Operation:** Up to 2.5Mbps  
- **Slew-Rate-Limited Driver:** Reduces EMI and reflections  
- **Full-Duplex Communication:** Independent driver and receiver  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation  
- **Enhanced ESD Protection:** ±15kV (Human Body Model)  
- **Wide Common-Mode Range:** -7V to +12V for robust noise immunity  
- **Fail-Safe Receiver:** Ensures logic-high output with open/short/terminated inputs  

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