Description and Introduction

Low-Voltage/ Single and Dual Supply/ 8 to 1 Multiplexer and Differential 4 to 1 Multiplexer The ISL43741IR is a quad SPST (Single-Pole Single-Throw) analog switch manufactured by **Intersil** (now part of Renesas Electronics). Below are its specifications, descriptions, and features based on available data:  

### **Specifications:**  
- **Configuration:** Quad SPST (4 independent switches)  
- **Supply Voltage Range:** ±4.5V to ±20V (Dual Supply), +4.5V to +36V (Single Supply)  
- **On-Resistance (RON):** 85Ω (typical at ±15V supply)  
- **On-Resistance Flatness:** 10Ω (typical)  
- **Charge Injection:** 5pC (typical)  
- **Bandwidth (-3dB):** 200MHz (typical)  
- **Switching Time (tON/tOFF):** 150ns / 100ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead QSOP  

### **Descriptions:**  
- The ISL43741IR is a high-performance, low-distortion analog switch designed for precision signal routing.  
- It supports both single and dual power supply operations, making it suitable for a variety of applications.  
- The device features low on-resistance and high bandwidth, ensuring minimal signal distortion.  

### **Features:**  
- Low On-Resistance (85Ω typical)  
- Wide Supply Voltage Range (±4.5V to ±20V, or +4.5V to +36V)  
- High Bandwidth (200MHz)  
- Low Charge Injection (5pC)  
- Fast Switching (150ns turn-on, 100ns turn-off)  
- Break-Before-Make Switching (prevents signal shorting)  
- TTL/CMOS Compatible Logic Inputs  
- Pb-Free, RoHS Compliant  

This device is commonly used in audio/video signal routing, test equipment, communication systems, and industrial control applications.
