Description and Introduction

【15kV ESD-Protected, Slew-Rate-Limited, Low-Power, RS-485/RS-422 Transceivers The MAX481EESA 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 (now Analog Devices)  
- **Part Number:** MAX481EESA  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** +4.5V to +5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Data Rate:** Up to 2.5Mbps  
- **Low Supply Current:**  
  - 120µA (Shutdown Mode)  
  - 0.3mA (Quiescent Current)  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Receiver Input Impedance:** 12kΩ (Minimum)  
- **Driver Output Short-Circuit Current Limit:** ±250mA  

### **Descriptions:**  
The MAX481EESA is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features a driver and receiver pair, making it suitable for half-duplex communication. The device includes thermal shutdown protection and is optimized for low-power applications.  

### **Features:**  
- **Low Power Consumption:** Ideal for battery-powered systems.  
- **Slew-Rate Limited Driver:** Reduces EMI and reflections in transmission lines.  
- **Half-Duplex Communication:** Single pair of driver/receiver for bidirectional data transfer.  
- **Thermal Shutdown Protection:** Prevents damage from excessive power dissipation.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Wide Common-Mode Voltage Range:** -7V to +12V for robust noise immunity.  
- **Compatible with RS-485 and RS-422 Standards.**  

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