Description and Introduction

LOW VOLTAGE LOW ON RESISTANCE SPDT SWITCH WITH BREAK BEFORE MAKE FEATURE The STG3157CTR is a high-speed, low-power dual SPDT (Single Pole Double Throw) analog switch manufactured by STMicroelectronics.  

### **Manufacturer:** STMicroelectronics  

### **Specifications:**  
- **Configuration:** Dual SPDT (Single Pole Double Throw)  
- **Supply Voltage Range (VCC):** 1.65V to 4.3V  
- **Low On-Resistance (RON):** 0.5Ω (typical at VCC = 4.3V)  
- **Low Power Consumption:** 0.1µA (typical at VCC = 4.3V)  
- **High-Speed Switching:** tON = 10ns, tOFF = 7ns (typical at VCC = 4.3V)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-10  

### **Descriptions and Features:**  
- Designed for high-speed signal switching in portable and battery-powered applications.  
- Low on-resistance ensures minimal signal distortion.  
- Wide supply voltage range makes it suitable for various logic levels.  
- Break-before-make switching action prevents signal shorting.  
- ESD protection (Human Body Model: 2000V).  
- Pb-free and RoHS compliant.  

This switch is commonly used in audio/video signal routing, communication systems, and data acquisition systems.

Application Scenarios & Design Considerations

LOW VOLTAGE LOW ON RESISTANCE SPDT SWITCH WITH BREAK BEFORE MAKE FEATURE

Alternative Part Number

  • TS5A3157DCKR --: Pin-compatible SPDT analog switch with similar low on-resistance and single-supply operation, widely available and a direct functional drop-in for the STG3157.
  • NLAS4157DFT2G --: SPDT analog switch in a comparable small package with similar voltage range and low Ron, suitable as a functional replacement.
  • MAX4626EUK+T --: Low-voltage SPDT analog switch offering similar switching characteristics and single-supply operation, usable as an alternative with minor layout considerations.
