Description and Introduction

Quad Analog Switch/Quad Multiplexer The MC14066 is a quad bilateral switch IC manufactured by ON Semiconductor. Here are its key specifications, descriptions, and features:

### **Manufacturer Specifications:**
- **Supply Voltage Range (VDD):** 3V to 18V  
- **On-Resistance (Ron):** Typically 200Ω at VDD = 15V  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation  
- **Operating Temperature Range:** -55°C to +125°C  
- **Input/Output Capacitance (Typical):** 5pF  
- **Breakdown Voltage (Input/Output):** 18V  

### **Descriptions:**
- The MC14066 consists of four independent bilateral switches that can control analog or digital signals.  
- Each switch has a control input, an input/output terminal, and an output/input terminal.  
- It is designed for bidirectional signal switching applications.  
- The IC is built using CMOS technology, ensuring high noise immunity and low power consumption.  

### **Features:**
- **Quad Bilateral Switch:** Four independent switches in a single package.  
- **Wide Voltage Range:** Operates from 3V to 18V, making it versatile for different applications.  
- **Low Crosstalk:** Minimizes interference between channels.  
- **High Off-Isolation:** Ensures minimal signal leakage when the switch is off.  
- **Matched Switch Characteristics:** Provides consistent performance across all four switches.  
- **Pin-Compatible with CD4066:** Allows for easy replacement in existing designs.  

The MC14066 is commonly used in signal routing, audio switching, analog multiplexing, and digital logic applications.

Application Scenarios & Design Considerations

Quad Analog Switch/Quad Multiplexer

Alternative Part Number

  • CD4066BE --: Pin-compatible quad bilateral switch with the same 4000-series CMOS function and widely available as a direct replacement.
  • HEF4066BP --: Quad bilateral analog switch equivalent to the MC14066, with matching pinout and supply voltage range.
  • TC4066BP --: Standard CMOS quad bilateral switch offering the same switching function and pin configuration as the original part.
  • 74HC4066D --: High-speed CMOS quad bilateral switch offering similar switching function with lower on-resistance and faster operation.
