Description and Introduction

Analog Multiplexer Demultiplexer High-Performance Silicon-Gate CMOS The part **IW4051BN** is a **CMOS analog multiplexer/demultiplexer** integrated circuit. Below are its key specifications, descriptions, and features based on available data:  

### **Manufacturer:**  
- **NXP Semiconductors** (formerly Philips Semiconductors)  

### **Description:**  
- The **IW4051BN** is a **single 8-channel analog multiplexer/demultiplexer** with three digital select inputs (A, B, C) and an inhibit input.  
- It allows bidirectional signal flow, making it suitable for both multiplexing and demultiplexing applications.  
- Built using **CMOS technology**, it provides low power consumption and high noise immunity.  

### **Key Features:**  
- **Analog Signal Handling:**  
  - Wide analog input voltage range (typically **±5V** with a **±7.5V** maximum).  
  - Low "ON" resistance (**~125Ω typical** at **VDD-VEE = 15V**).  
- **Digital Control:**  
  - Three binary control inputs (**A, B, C**) for channel selection.  
  - **Inhibit (INH) input** to disable all channels.  
- **Power Supply:**  
  - **Wide supply voltage range (3V to 20V)**.  
  - Compatible with **TTL and CMOS logic levels**.  
- **Low Power Consumption:**  
  - **Quiescent current: ~1µA (max) at 20V**.  
- **Break-Before-Make Switching:**  
  - Prevents signal overlap during channel switching.  

### **Applications:**  
- Signal routing in **audio/video systems**.  
- **Data acquisition systems**.  
- **Analog-to-digital conversion (ADC) multiplexing**.  
- **Communication systems**.  

### **Package:**  
- Typically available in a **DIP-16 (Dual In-line Package)**.  

This information is based on the standard **4051B series** specifications, as the exact datasheet for **IW4051BN** may not be publicly available. For precise details, refer to the official **NXP datasheet**.

Application Scenarios & Design Considerations

Analog Multiplexer Demultiplexer High-Performance Silicon-Gate CMOS

Alternative Part Number

  • CD4051BE --: Pin-compatible CMOS 8-channel analog multiplexer/demultiplexer with the same function and DIP-16 package; widely available and a direct functional drop-in.
  • MC14051BCP --: Equivalent 8-channel analog multiplexer/demultiplexer in DIP-16 with matching pinout and logic levels; a well-established second source.
  • HEF4051BP --: Standard 4051-series analog multiplexer/demultiplexer in DIP-16, functionally identical and suitable as a replacement when the original is unavailable.
