- **Package:** **SSOP-16**  
- **ESD Protection:** **±15 kV (Human Body Model)**  

### **Descriptions:**  
- The **TRS3222EIDBR** is a low-power, dual-channel RS-232 transceiver designed for **3V to 5.5V** operation.  
- It complies with **TIA/EIA-232-F** standards and supports **full-duplex** communication.  
- Includes an **integrated charge pump** for generating RS-232 voltage levels from a single supply.  
- Suitable for **battery-powered** and **portable applications** due to its low power consumption.  

### **Features:**  
- **Auto-Powerdown** feature for reduced power consumption when inactive.  
- **Enhanced ESD Protection** (±15 kV HBM) for robustness.  
- **Wide Supply Voltage Range (3V to 5.5V)** for flexibility.  
- **Small Footprint (SSOP-16 Package)** for space-constrained designs.  
- **On-Chip Capacitors** eliminate the need for external charge-pump capacitors.
