### **Specifications:**
- **Supply Voltage Range:** 3.0V to 5.5V  
- **Data Rate:** Up to 250kbps  
- **Number of Drivers/Receivers:** 1 driver, 1 receiver  
- **ESD Protection:** ±15kV (Human Body Model)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-pin SSOP (Shrink Small Outline Package)  

### **Descriptions:**
The MAX3221EEAE is a low-power, single-channel RS-232 transceiver designed for serial communication applications. It integrates a charge pump to generate RS-232 voltage levels from a single 3.0V to 5.5V supply, eliminating the need for external power supplies. It is suitable for battery-powered and portable devices.

### **Features:**
- **Auto-Shutdown Plus:** Automatically powers down when the RS-232 cable is disconnected, reducing power consumption.  
- **Low Power Consumption:** 1µA supply current in shutdown mode.  
- **Enhanced ESD Protection:** Protects against electrostatic discharge up to ±15kV.  
- **Compliance:** Meets EIA/TIA-232 and V.28/V.24 standards.  
- **Small Footprint:** Available in a space-saving SSOP package.  

This device is commonly used in industrial, medical, and consumer electronics requiring reliable RS-232 communication.
