Description and Introduction

Analog MultiplexerDemultiplexer The MC14051BF is a single 8-channel analog multiplexer/demultiplexer manufactured by Motorola.  

### **Specifications:**  
- **Supply Voltage Range (VDD):** 3V to 18V  
- **Low "ON" Resistance:** 125Ω (typical) at VDD = 15V  
- **High Noise Immunity:** 0.45 VDD (typical)  
- **Low Power Consumption:** 10nW (typical) at VDD = 5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Logic Level Conversion:** Compatible with standard CMOS, PMOS, and NMOS  
- **Package Type:** 16-pin SOIC (Small Outline Integrated Circuit)  

### **Descriptions and Features:**  
- The MC14051BF is a digitally controlled analog switch that can function as either a multiplexer or demultiplexer.  
- It consists of eight bidirectional switches with a common input/output (I/O) pin and individual switch control inputs.  
- The device is designed for analog and digital signal switching applications.  
- It features low crosstalk and high OFF isolation.  
- The MC14051BF is part of Motorola’s 4000B series CMOS logic family, known for low power consumption and high noise immunity.  
- Applications include signal gating, chopping, modulation, and analog-to-digital conversion.  

This information is based solely on Motorola's technical documentation for the MC14051BF.

Application Scenarios & Design Considerations

Alternative Part Number

  • CD4051BE --: Pin-compatible CMOS 8-channel analog multiplexer/demultiplexer with the same function and DIP-16 package; widely available and directly interchangeable in most designs.
  • HEF4051BP --: Equivalent 8-channel analog multiplexer/demultiplexer from the HEF4000 series, same pinout and supply range, a common drop-in replacement for the MC14051BF.
  • CD74HC4051E --: High-speed CMOS 8-channel analog multiplexer with identical pin configuration in DIP-16, suitable when faster switching or lower on-resistance is acceptable.
