Description and Introduction

Low-Voltage/ Single and Dual Supply/ Quad SPST/ High Performance Analog Switches The ISL43144IR 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 Ic-phoenix technical data files:

### **Specifications:**  
- **Supply Voltage Range (V+ to V-):** ±4.5V to ±20V  
- **On-Resistance (RON):** 85Ω (typical) at ±15V supply  
- **Low Charge Injection:** 10pC (typical)  
- **Fast Switching Time:**  
  - tON: 150ns (typical)  
  - tOFF: 100ns (typical)  
- **Low Power Consumption:** 0.5µW (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
The ISL43144IR is a high-performance, quad SPST analog switch designed for precision signal switching applications. It features low on-resistance, fast switching speeds, and minimal charge injection, making it suitable for audio, video, and data acquisition systems.  

### **Features:**  
- **Quad SPST Configuration:** Four independent switches in a single package.  
- **Wide Supply Voltage Range:** Supports bipolar (±4.5V to ±20V) and single-supply (9V to 40V) operation.  
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **High Off-Isolation:** >80dB at 1MHz.  
- **Break-Before-Make Switching:** Prevents signal overlap during switching.  
- **TTL/CMOS Compatible Logic Inputs:** Easy interface with digital control circuits.  
- **ESD Protection:** Up to 2kV (Human Body Model).
