Description and Introduction

LOW VOLTAGE 4OHM SPDT SWITCH The STG719STR is a high-speed, low-power SPDT (Single Pole Double Throw) analog switch manufactured by STMicroelectronics.  

### **Key Specifications:**  
- **Supply Voltage Range (VCC):** 1.8V to 5.5V  
- **Low On-Resistance (RON):** 0.5Ω (typical at 4.5V)  
- **Bandwidth (-3dB):** 500MHz  
- **Low Power Consumption:** 0.1µA (typical)  
- **Fast Switching Time (tON/tOFF):** 20ns / 15ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions and Features:**  
- Designed for high-speed signal switching in portable and battery-powered applications.  
- Low insertion loss and high off-isolation for improved signal integrity.  
- Break-before-make switching to prevent signal shorting.  
- TTL/CMOS-compatible control inputs.  
- ESD protection: >2000V (HBM)  

The STG719STR is suitable for applications such as audio/video switching, communication systems, and data routing.

Application Scenarios & Design Considerations

LOW VOLTAGE 4OHM SPDT SWITCH

Alternative Part Number

  • TS5A3157DBVR --: Single SPDT analog switch in SOT-23-6 with similar low on-resistance and 1.8-5.5V operation, a common pin-compatible alternative to the STG719.
  • NLAS4157DFT2G --: Low-voltage SPDT analog switch in a small package with comparable Ron and switching characteristics, suitable as a functional replacement.
  • MAX4544EUT+T --: SPDT analog switch with low on-resistance and single-supply operation, offering similar signal routing performance for the same application.
