Description and Introduction

High-Speed, Low-Voltage, 4з, Dual SPST CMOS Analog Switches The MAX4642EUA is a high-performance, low-voltage, single-pole/double-throw (SPDT) analog switch manufactured by Maxim Integrated (now part of Analog Devices).  

### **Specifications:**  
- **Supply Voltage (V+ to GND):** +1.8V to +5.5V  
- **Low On-Resistance (RON):** 0.8Ω (typical at +5V supply)  
- **Low On-Resistance Flatness:** 0.3Ω (typical)  
- **Fast Switching Time:**  
  - **tON (Turn-On Time):** 35ns (typical)  
  - **tOFF (Turn-Off Time):** 20ns (typical)  
- **Low Charge Injection:** 10pC (typical)  
- **High Off-Isolation:** -50dB at 1MHz  
- **Low Power Consumption:** 0.1µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin µMAX (microMAX)  

### **Description:**  
The MAX4642EUA is a CMOS analog switch designed for high-speed, low-distortion signal switching applications. It is ideal for battery-powered and portable devices due to its low power consumption and wide supply voltage range.  

### **Features:**  
- **Low On-Resistance (0.8Ω at +5V)**  
- **Wide Supply Voltage Range (1.8V to 5.5V)**  
- **Fast Switching Speed (tON = 35ns, tOFF = 20ns)**  
- **Low Power Consumption (0.1µA typical)**  
- **High Off-Isolation (-50dB at 1MHz)**  
- **Low Charge Injection (10pC typical)**  
- **TTL/CMOS-Logic Compatible**  
- **8-Pin µMAX Package**  

This switch is commonly used in audio/video signal routing, communication systems, and battery-operated devices.
