Description and Introduction

SINGLE BILATERAL ANALOG SWITCH The SN74LVC1G66YEAR is a single-pole single-throw (SPST) analog switch manufactured by Texas Instruments.  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Analog Switch  
- **Configuration:** SPST (Single-Pole Single-Throw)  
- **Number of Channels:** 1  
- **Supply Voltage Range:** 1.65V to 5.5V  
- **On-State Resistance (RON):** 6Ω (typical) at 5V  
- **Low Power Consumption:** ICC = 0.1µA (max)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions and Features:**  
- **Low Voltage Operation:** Supports 1.65V to 5.5V, making it suitable for mixed-voltage applications.  
- **Bidirectional Switching:** Allows signals to pass in both directions when enabled.  
- **Low On-State Resistance:** Ensures minimal signal distortion.  
- **Fast Switching:** Enables high-speed signal routing.  
- **Low Power Consumption:** Ideal for battery-powered devices.  
- **Break-Before-Make Switching:** Prevents signal overlap during switching.  
- **ESD Protection:** HBM (Human Body Model) > 2000V for improved reliability.  

This device is commonly used in portable electronics, signal routing, and data acquisition systems.

Application Scenarios & Design Considerations

SINGLE BILATERAL ANALOG SWITCH

Alternative Part Number

  • NC7SZ66P5X --: Single-pole single-throw analog switch in a similar tiny package, functionally equivalent to the SN74LVC1G66 and widely available.
  • 74LVC1G66GW,125 --: Direct functional equivalent single analog switch from a different series/prefix, with comparable LVC logic family characteristics.
  • TS5A3166DBVR --: TI single-channel analog switch with similar on-resistance and supply range, usable as a drop-in functional replacement.
  • 74LVC1G66GW --: Same LVC-family single analog switch function with comparable voltage range and low on-resistance, offered by a major alternate vendor.
  • TS5A3166DCKR --: Single-channel analog switch with similar signal-switching characteristics, useful when a different TI series is preferred for sourcing flexibility.
