Description and Introduction

8-CHANNEL ANALOG MULTIPLEXERS/DEMULTIPLEXERS The SN74LV4051ADB 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:** 80 Ω (typical at 5 V)  
- **Low Power Consumption:** ICC = 4 μA (max)  
- **Wide Analog Input Voltage Range:** 0 V to VCC  
- **Digital Control Input Voltage Range:** 0 V to VCC  
- **Break-Before-Make Switching:** Prevents signal distortion  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP (DB) – 16-pin  

### **Description:**  
The SN74LV4051ADB is a CMOS-based analog switch that allows one of eight analog/digital signals to be routed to a common output (or vice versa for demultiplexing). It is designed for low-voltage operation and provides bidirectional signal transmission.  

### **Features:**  
- **Single 8-Channel Multiplexer/Demultiplexer**  
- **Low On-State Resistance (80 Ω at 5 V)**  
- **Wide Operating Voltage Range (2 V to 5.5 V)**  
- **Low Power Consumption (4 μA max ICC)**  
- **Break-Before-Make Switching**  
- **Supports Bidirectional Signal Flow**  
- **ESD Protection Exceeds 2000 V (HBM)**  
- **Available in SSOP-16 Package**  

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

Application Scenarios & Design Considerations

8-CHANNEL ANALOG MULTIPLEXERS/DEMULTIPLEXERS

Alternative Part Number

  • CD74HC4051E --: Same 8-channel analog multiplexer/demultiplexer function with similar supply range and pinout, from a different TI logic family, making it a direct functional substitute.
  • MC74HC4051ADG --: Pin-compatible 8-channel analog multiplexer/demultiplexer with comparable on-resistance and supply voltage range, offered by an alternate manufacturer.
  • HEF4051BT --: Standard 4051-series 8-channel analog multiplexer/demultiplexer with similar electrical characteristics, suitable as a cross-manufacturer replacement.
