Description and Introduction

Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers The MAX481CSA 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:** MAX481CSA  
- **Type:** RS-485/RS-422 Low-Power Transceiver  
- **Supply Voltage Range:** +4.75V to +5.25V  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Data Rate:** Up to 2.5Mbps  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Quiescent Current:** 120µA (Typical)  
- **Shutdown Current:** 0.1µA (Typical)  

### **Descriptions:**  
The MAX481CSA is a low-power, slew-rate-limited transceiver designed for RS-485 and RS-422 communication. It features a single driver and receiver, making it suitable for half-duplex applications. The device includes a low-power shutdown mode, reducing current consumption to 0.1µA when not in use. It is commonly used in industrial control systems, automotive networks, and other applications requiring robust differential communication.  

### **Features:**  
- Low-power operation (120µA quiescent current)  
- Slew-rate-limited for reduced EMI  
- Shutdown mode with 0.1µA current consumption  
- ESD protection (±15kV)  
- Driver short-circuit current limiting  
- Thermal shutdown protection  
- Half-duplex communication  
- Operates from a single +5V supply  

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