- **Package:** 16-VQFN (3mm x 3mm)  

### **Descriptions:**  
The TS3A44159RGTR is a high-performance, low-voltage, bidirectional analog switch designed for signal routing in portable and low-power applications. It features low on-resistance and minimal propagation delay, making it suitable for audio, data, and video signal switching.  

### **Features:**  
- **Wide Supply Voltage Range (1.8V to 5.5V)**  
- **Low On-Resistance (0.9Ω typical at 4.5V)**  
- **Low Power Consumption (0.5µA max at 5.5V)**  
- **Break-Before-Make Switching for Signal Integrity**  
- **Bidirectional Signal Path**  
- **ESD Protection (HBM: 2kV)**  
- **Small 16-VQFN Package for Space-Constrained Designs**  

This switch is commonly used in portable devices, communication systems, and signal multiplexing applications.
