3.3V Low Power Half-Duplex RS-485 Transceivers with 10Mbps Data Rate The SP3485EP is a low-power transceiver manufactured by SP (Sipex) that is designed for RS-485 and RS-422 communication.  

### **Specifications:**  
- **Supply Voltage:** 3.0V to 3.6V  
- **Data Rate:** Up to 10Mbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **Half-Duplex Communication**  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Low Power Consumption:**  
  - **Shutdown Current:** <1µA  
  - **Active Current:** 300µA (typical)  
- **Package:** 8-pin SOIC  

### **Descriptions:**  
- The SP3485EP is a 3.3V RS-485/RS-422 transceiver optimized for high-speed, low-power applications.  
- It is compatible with industry-standard RS-485 and RS-422 protocols.  
- The device features a slew-rate-limited driver to minimize EMI and reduce reflections in improperly terminated networks.  

### **Features:**  
- **3.3V Operation**  
- **Enhanced ESD Protection**  
- **1/8 Unit Load (Allows up to 256 nodes on a bus)**
