### **Specifications:**  
- **Supply Voltage:** 3.0V to 5.5V  
- **Data Rate:** Up to 235 kbps  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin TSSOP  
- **Number of Drivers/Receivers:** 1 Driver, 1 Receiver  
- **ESD Protection:** ±15kV (Human Body Model)  

### **Descriptions:**  
- The SP3220EET is a low-power, 3.3V RS-232 transceiver designed for serial communication applications.  
- It complies with EIA/TIA-232-F standards and is suitable for battery-powered devices.  
- The device includes an onboard charge pump, eliminating the need for external ±12V power supplies.  

### **Features:**  
- **Low Power Consumption:** Auto Powerdown feature reduces current consumption when not in use.
