Description and Introduction

8-Channel Analog Multiplexer/Demultiplexer The SN74LV4051ADR is a single 8-channel analog multiplexer/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2 V to 5.5 V  
- **Low On-State Resistance:** 80 Ω (typical at 5 V)  
- **Low Power Consumption:** 0.2 µA (typical at 5 V)  
- **Wide Analog Input Voltage Range:** ±5 V (max at 5 V supply)  
- **Digital Input Voltage Range:** 0 V to VCC  
- **Break-Before-Make Switching**  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Description:**  
The SN74LV4051ADR is a CMOS-based analog switch that allows bidirectional signal flow. It can function as either an 8:1 multiplexer or a 1:8 demultiplexer, controlled by three binary select inputs (A, B, C).  

### **Features:**  
- **Low Voltage Operation:** Supports 2 V to 5.5 V  
- **High Noise Immunity**  
- **Low Crosstalk Between Channels**  
- **TTL-Compatible Input Levels**  
- **ESD Protection Exceeds 2000 V (HBM)**  
- **Latch-Up Performance Exceeds 250 mA**  

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

Application Scenarios & Design Considerations

8-Channel Analog Multiplexer/Demultiplexer

Alternative Part Number

  • CD74HC4051M --: 8-channel analog multiplexer/demultiplexer in the same SOIC-16 package with similar on-resistance and supply range, widely available and pin-compatible.
  • MC74VHC4051DR2G --: Pin-compatible 8-channel analog multiplexer/demultiplexer in SOIC-16 with comparable low-voltage operation and low on-resistance.
  • 74HC4051D --: Standard 8-channel analog multiplexer/demultiplexer in SOIC-16, functionally equivalent with similar supply voltage range and switching characteristics.
  • CD74HC4051M96 --: Same 8-channel analog multiplexer/demultiplexer function in SOIC-16, HC family is a widely used drop-in alternative to LV4051 with similar pinout and switching behavior.
  • MC74HC4051ADG --: Pin-compatible 8-channel analog multiplexer/demultiplexer in SOIC-16 from a different series, offering equivalent channel selection and analog signal routing.
  • HEF4051BT --: Classic 4051 8-channel analog multiplexer/demultiplexer in SOIC-16, functionally equivalent for analog switching applications with broad availability.
