Description and Introduction

Enhanced Low Power Half-Duplex RS-485 Transceivers The SP481EEP is a RS-485/RS-422 transceiver manufactured by SIPEX (now part of Exar Corporation). Below are its specifications, descriptions, and features based on available information:

### **Specifications:**  
- **Supply Voltage:** +5V  
- **Data Rate:** Up to 10Mbps  
- **Operating Temperature:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Interface Type:** RS-485/RS-422  
- **Package:** 8-pin DIP or SOIC  

### **Descriptions:**  
- The SP481EEP is a low-power, high-speed transceiver designed for RS-485 and RS-422 communication.  
- It features a differential driver and receiver, making it suitable for noise-immune data transmission over long distances.  
- The device includes thermal shutdown protection and is compliant with industry standards for RS-485/RS-422 communication.  

### **Features:**  
- **High-Speed Operation:** Supports data rates up to 10Mbps.  
- **Low Power Consumption:** Designed for power-sensitive applications.  
- **ESD Protection:** Built-in electrostatic discharge (ESD) protection (±15kV Human Body Model).  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Half-Duplex Operation:** Suitable for bidirectional communication on a single pair of wires.  
- **Wide Common-Mode Range:** Allows operation in noisy environments.
