### **Descriptions:**
The ISL43143IV is a high-performance, low on-resistance analog switch designed for precision signal routing in industrial, medical, and communication applications. It features low charge injection and high bandwidth, making it suitable for high-speed data acquisition and signal processing.

### **Features:**
- Low On-Resistance (45Ω typical)
- Wide Supply Voltage Range (±4.5V to ±20V)
- Fast Switching Speed (150ns turn-on, 100ns turn-off)
- High Off-Isolation (>80dB at 1MHz)
- Low Charge Injection (5pC)
- Break-Before-Make Switching Action
- TTL/CMOS Compatible Logic Inputs
- Pb-Free (RoHS Compliant)

This switch is ideal for applications requiring high precision and fast signal switching, such as multiplexers, sample-and-hold circuits, and audio/video routing.
