Description and Introduction

Ultra Low ON-Resistance, Low Voltage, Single Supply, Dual SPDT Analog Switch The ISL84684IU is a high-performance, low-voltage, single-pole, double-throw (SPDT) analog switch manufactured by Intersil (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** 1.8V to 5.5V  
- **On-Resistance (Ron):** 0.6Ω (typical at 4.5V supply)  
- **Low Power Consumption:** 0.1μA (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Charge Injection:** 10pC (typical)  
- **Off Isolation:** -70dB at 1MHz  
- **Crosstalk Rejection:** -80dB at 1MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 10-Lead TDFN (3mm x 3mm)  

### **Descriptions:**
- The ISL84684IU is a bidirectional, low-voltage SPDT analog switch designed for high-speed signal switching.  
- It is optimized for low on-resistance and minimal propagation delay, making it suitable for portable and high-frequency applications.  
- The device features break-before-make switching to prevent signal distortion.  

### **Features:**
- **Low On-Resistance:** Ensures minimal signal attenuation.  
- **Wide Supply Range:** Operates from 1.8V to 5.5V, compatible with various logic levels.  
- **Fast Switching:** tON = 20ns, tOFF = 10ns (typical at 5V).  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **High Bandwidth:** Supports high-frequency signal routing.  
- **Break-Before-Make Switching:** Prevents signal shorting during transitions.  
- **ESD Protection:** ±8kV (Human Body Model).  

This device is commonly used in audio/video switching, portable devices, communication systems, and test equipment.
