Description and Introduction

8-Channel Analog Multiplexer/Demultiplexer with Injection-Current Effect Control The SN74HC4851DR is a single 8-channel analog multiplexer/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2V to 6V  
- **Low ON-State Resistance:** 70Ω (typical) at 4.5V  
- **Low Power Consumption:** 0.8µA (max) at 6V  
- **High Noise Immunity:** CMOS technology  
- **Break-Before-Make Switching:** Prevents signal shorting  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
The SN74HC4851DR is a digitally controlled analog switch that routes one of eight inputs to a common output (or vice versa). It is designed for bidirectional signal switching and is compatible with standard CMOS logic levels.  

### **Features:**  
- **Wide Analog Input Voltage Range:** 0V to VCC  
- **Low Crosstalk Between Channels**  
- **Fast Switching:** tPD = 13ns (typical) at 6V  
- **TTL-Compatible Input Levels**  
- **ESD Protection Exceeds 2000V (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 with Injection-Current Effect Control

Alternative Part Number

  • CD74HC4051M --: 8-channel analog multiplexer/demultiplexer in the same SOIC-16 package with similar on-resistance and supply range, widely used as a functional substitute for the HC4851.
  • MC74HC4051ADG --: Pin-compatible 8-channel analog mux/demux with comparable Ron and voltage ratings, available from a second source for supply flexibility.
  • ADG508AKRZ --: 8-channel analog multiplexer with low on-resistance and similar logic-level control, suitable when improved switch performance is needed.
