Description and Introduction

3.3V Low Power Half-Duplex RS-485 Transceivers with 10Mbps Data Rate The SP3485CP is a low-power half-duplex RS-485 transceiver manufactured by Exar Corporation (now part of MaxLinear).  

### **Specifications:**  
- **Supply Voltage:** 3.3V  
- **Data Rate:** Up to 10 Mbps  
- **Operating Temperature Range:** 0°C to +70°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:**  
  - **Supply Current (Active Mode):** 1.5 mA (typical)  
  - **Supply Current (Shutdown Mode):** 1 µA (typical)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The SP3485CP is designed for RS-485 and RS-422 communication in industrial and commercial applications.  
- It supports half-duplex communication, allowing bidirectional data transmission over a single twisted-pair cable.  
- The device features a low-power shutdown mode to conserve energy in battery-operated systems.  

### **Features:**  
- **3.3V Operation** – Compatible with 3.3V logic levels.  
- **Enhanced ESD Protection** – Protects against electrostatic discharge.  
- **Driver Output Short-Circuit Protection** – Ensures reliability in fault conditions.  
- **Receiver Open-Circuit Fail-Safe** – Ensures a logic-high output when inputs are open.  
- **Industry-Standard Pinout** – Compatible with similar RS-485 transceivers.  

The SP3485CP is commonly used in industrial automation, building control, and point-of-sale systems.
