Description and Introduction

Low voltage 0.5 Ω max dual SPDT switch with break-before-make The STG3684ADTR is a high-speed, low-voltage dual SPDT (Single Pole Double Throw) analog switch manufactured by STMicroelectronics (STM).  

### **Specifications:**  
- **Configuration:** Dual SPDT (2 channels)  
- **Supply Voltage Range:** 1.65V to 4.3V  
- **Low On-Resistance:** 0.5Ω (typical) at 4.3V  
- **Low Power Consumption:**  
  - Static Current: <1μA (max)  
  - Dynamic Current: <0.1μA (max)  
- **High-Speed Switching:**  
  - Turn-On Time (tON): 20ns (typical)  
  - Turn-Off Time (tOFF): 15ns (typical)  
- **Break-Before-Make Switching:** Ensures no signal overlap  
- **ESD Protection:**  
  - Human Body Model (HBM): 2000V  
  - Machine Model (MM): 200V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-14  

### **Descriptions & Features:**  
- Designed for high-speed signal switching in portable and battery-powered applications.  
- Low-voltage operation makes it suitable for 1.8V, 2.5V, and 3.3V systems.  
- Break-before-make feature prevents signal shorting during switching.  
- Low on-resistance ensures minimal signal distortion.  
- Suitable for audio, video, data switching, and multiplexing applications.  
- Pb-free and RoHS compliant.
