Description and Introduction

8-Channel Analog Multiplexer/Demultiplexer The SN74LV4051ANSR is a single 8-channel analog multiplexer/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range (VCC):** 2 V to 5.5 V  
- **Low On-State Resistance:** 70 Ω (typical) at 5 V  
- **Low Power Consumption:** 0.2 µA (typical) at 5 V  
- **Wide Analog Input Voltage Range:** 0 V to VCC  
- **Break-Before-Make Switching**  
- **Operating Temperature Range:** -40°C to 85°C  
- **Package:** SOIC-16 (NSR)  

### **Description:**  
The SN74LV4051ANSR is a digitally controlled analog switch that can function as an 8:1 multiplexer or 1:8 demultiplexer. It is designed for low-voltage operation and features low power consumption, making it suitable for battery-powered applications.  

### **Features:**  
- **Low Voltage Operation (2 V to 5.5 V)**  
- **Low On-State Resistance (70 Ω at 5 V)**  
- **Minimal Power Consumption (0.2 µA at 5 V)**  
- **Wide Analog Signal Range (0 V to VCC)**  
- **Break-Before-Make Switching to Prevent Signal Overlap**  
- **Compatible with TTL and CMOS Logic Levels**  
- **ESD Protection Exceeds 2000 V (HBM)**  

This device is commonly used in signal routing, data acquisition, and audio/video switching applications.

Application Scenarios & Design Considerations

8-Channel Analog Multiplexer/Demultiplexer

Alternative Part Number

  • CD74HC4051M96 --: Same 8-channel analog multiplexer/demultiplexer function in SOIC-16 package, HC family with similar supply range and pinout, widely available and drop-in compatible in most designs.
  • MC74HC4051ADTR2G --: Pin-compatible 8-channel analog mux/demux in SOIC-16 with comparable on-resistance and supply voltage range, a common second-source alternative to the LV4051.
  • 74HC4051D,653 --: Standard 8-channel analog multiplexer/demultiplexer in SOIC-16, functionally equivalent with similar switching characteristics, suitable as a lower-cost alternative.
