### **Descriptions:**  
The STG3220QTR is a dual supply voltage level translator designed for bidirectional voltage translation between different logic levels. It supports automatic direction sensing, eliminating the need for a direction control pin.  

### **Features:**  
- **Bidirectional Voltage Translation:** No direction control signal required  
- **Wide Voltage Range Support:** 1.2V to 5.5V  
- **High-Speed Performance:** Suitable for fast signal switching  
- **Low Power Consumption:** Ideal for battery-operated devices  
- **Auto-Direction Sensing:** Simplifies design and reduces pin count  
- **Robust ESD Protection:** Ensures reliability in harsh environments  

This device is commonly used in mixed-voltage systems, such as interfacing between microcontrollers, FPGAs, and other digital ICs with different supply voltages.
