Description and Introduction

Quadruple Bilateral Analog Switches The SN74HC4066DBR is a quad bilateral switch manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Analog Switches, Multiplexers, Demultiplexers  
- **Configuration:** 4 x SPST (Single-Pole, Single-Throw)  
- **On-State Resistance (Max):** 70 Ohms  
- **On-State Resistance Flatness (Max):** 10 Ohms  
- **Supply Voltage Range:** 2V to 6V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package / Case:** SSOP-14  
- **Switching Time (Ton/Toff):** 30ns (typical)  
- **Charge Injection:** 7pC (typical)  
- **Leakage Current (Max):** ±100nA  
- **Logic Voltage - VIL, VIH:** 1.5V / 3.15V (at 4.5V supply)  

### **Description:**  
The SN74HC4066DBR is a high-speed CMOS analog switch designed for signal routing in digital and analog applications. It features low on-state resistance, minimal charge injection, and high bandwidth, making it suitable for audio, video, and data switching.

### **Features:**  
- **Low Power Consumption:** CMOS technology ensures minimal power dissipation.  
- **Wide Operating Voltage:** Supports 2V to 6V supply range.  
- **High Noise Immunity:** CMOS design reduces susceptibility to noise.  
- **Break-Before-Make Switching:** Prevents signal overlap during transitions.  
- **Bidirectional Signal Flow:** Allows signals to pass in either direction.  
- **ESD Protection:** Exceeds 2000V (HBM) for improved reliability.  
- **SSOP-14 Package:** Compact surface-mount form factor.  

This device is commonly used in audio/video switching, signal gating, and multiplexing applications.
