### **Specifications:**  
- **Supply Voltage Range:** ±4.5V to ±20V (Dual Supply) or +4.5V to +36V (Single Supply)  
- **On-Resistance (RON):** 85Ω (Typical)  
- **Low Power Consumption:** 0.5µW (Typical)  
- **Fast Switching Time:** tON = 200ns, tOFF = 100ns  
- **Break-Before-Make Switching Action**  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP  

### **Description:**  
The ISL8491IP is a high-voltage, precision analog switch designed for signal routing in industrial and instrumentation applications. It offers low on-resistance and high-voltage handling capability, making it suitable for both single and dual supply systems.  

### **Features:**  
- **Wide Supply Voltage Range** (Single or Dual Supply)  
- **Low On-Resistance** (85Ω typical)  
- **Low Power Consumption**  
- **Break-Before-Make Switching** (Prevents signal overlap)  
- **High Off-Isolation**  
- **TTL/CMOS Compatible Logic Inputs**  
- **ESD Protection** (≥2kV HBM)  

This switch is commonly used in audio, video, and data acquisition systems where precision signal routing is required.  

(Note: Since Intersil was acquired by Renesas Electronics, availability may vary.)
