Description and Introduction

Low-Voltage/ Single and Dual Supply/ Quad SPDT/ High Performance Analog Switches The ISL43240IR is a quad SPST (Single-Pole Single-Throw) analog switch manufactured by **Intersil** (now part of Renesas Electronics). Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Configuration:** Quad SPST (4 independent switches)  
- **Supply Voltage Range:** ±4.5V to ±20V (dual supply), +4.5V to +40V (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 SOIC  

### **Description:**  
The ISL43240IR is a high-performance, low-voltage, quad analog switch designed for precision signal routing in industrial, communications, and test equipment. It supports both single and dual power supplies and offers low distortion for high-frequency signals.

### **Features:**  
- **Wide Voltage Range:** Supports ±20V dual supply or +40V single supply.  
- **Low On-Resistance:** 85Ω (typical) ensures minimal signal attenuation.  
- **High Bandwidth:** 200MHz enables high-speed signal switching.  
- **Low Charge Injection:** 5pC reduces glitches during switching.  
- **Break-Before-Make (BBM) Switching:** Prevents signal overlap.  
- **TTL/CMOS Compatible Logic Inputs:** Ensures easy interfacing with digital circuits.  
- **Low Power Consumption:** Ideal for battery-operated systems.
