### **Descriptions:**
The TRS3243ECDBR is a 3-V to 5.5-V powered RS-232 transceiver designed for serial data communication. It integrates charge-pump circuitry to generate RS-232 voltage levels from a single supply, eliminating the need for external power supplies. The device is compliant with EIA/TIA-232-F standards and supports multiple drivers and receivers for full-duplex communication.

### **Features:**
- Operates from a **single 3-V to 5.5-V supply**  
- **Auto-powerdown** feature for power savings  
- **Enhanced ESD protection** (up to ±15 kV)  
- **Meets or exceeds TIA/EIA-232-F standards**  
- **Interoperable with 3.3-V or 5-V logic**  
- **Small footprint SSOP-28 package**  
- **Low standby current** (1 µA typical)  

This device is commonly used in **industrial, telecom, and computing applications** requiring robust RS-232 communication.
