Description and Introduction

LOW VOLTAGE 5OHM MAX DUAL SPDT SWITCH WITH BREAK BEFORE MAKE FEATURE The STG3680QTR is a high-speed, low-voltage, dual SPDT (Single Pole Double Throw) analog switch manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Supply Voltage (VCC):** 1.65V to 4.3V  
- **Low On-Resistance (RON):** 0.5Ω (typical) at 4.3V  
- **Bandwidth:** 900MHz (typical)  
- **Low Power Consumption:** 0.1μA (max) at 25°C  
- **Fast Switching Time:** tON = 10ns, tOFF = 7ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** QFN-10 (2x2mm)  

### **Description:**  
The STG3680QTR is designed for high-speed signal switching in portable and battery-powered applications. It features low on-resistance and minimal propagation delay, making it suitable for USB, audio, and data routing applications.  

### **Features:**  
- Dual SPDT configuration  
- Break-before-make switching  
- ESD Protection: 2kV (HBM)  
- Low charge injection  
- Pb-free and RoHS compliant  

This switch is ideal for applications requiring minimal signal distortion and high-speed operation.
