Description and Introduction

Enhanced Low EMI Half-Duplex RS-485 Transceiver The SP483ECP is a transceiver manufactured by Sipex (now part of Exar Corporation). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:  

### **Specifications:**  
- **Type:** RS-485/RS-422 Transceiver  
- **Supply Voltage:** 4.5V to 5.5V  
- **Data Rate:** Up to 10Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Package:** 8-Pin DIP, SOIC  

### **Descriptions:**  
- The SP483ECP is a low-power, high-speed transceiver designed for RS-485 and RS-422 communication.  
- It supports half-duplex communication and features slew-rate-limited outputs to minimize EMI.  
- The device is suitable for industrial, automotive, and networking applications.  

### **Features:**  
- **Low Power Consumption:** Typically 300µA in shutdown mode.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge.  
- **Slew-Rate Limited Outputs:** Reduces EMI and reflections in transmission lines.  
- **Wide Common-Mode Voltage Range:** Supports -7V to +12V for noise immunity.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.
