Description and Introduction

Low-Voltage/ Single Supply/ SPST/ High Performance Analog Switches The ISL43111IB is a single-pole, single-throw (SPST) analog switch manufactured by INTERSIL (now part of Renesas Electronics). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Supply Voltage Range:** ±4.5V to ±20V (Dual Supply) or +9V to +40V (Single Supply)  
- **On-Resistance (RON):** 85Ω (Typical) at ±15V Supply  
- **Charge Injection:** 10pC (Typical)  
- **Bandwidth (-3dB):** 100MHz  
- **Switching Time (tON/tOFF):** 200ns / 150ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead PDIP  

### **Descriptions:**
- The ISL43111IB is a high-performance, low-voltage, bidirectional analog switch designed for precision signal switching applications.  
- It features low on-resistance, fast switching, and minimal charge injection, making it suitable for audio, video, and data acquisition systems.  
- The device operates with both single and dual power supplies, providing flexibility in various circuit designs.  

### **Features:**
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **High Bandwidth:** Supports high-frequency signal switching.  
- **Low Charge Injection:** Reduces glitches during switching.  
- **Wide Supply Range:** Compatible with both single and dual supplies.  
- **Break-Before-Make Switching:** Prevents signal overlap during transitions.  
- **ESD Protection:** Robust protection against electrostatic discharge.  

This information is based solely on the manufacturer's datasheet for the ISL43111IB.

Application Scenarios & Design Considerations

Low-Voltage/ Single Supply/ SPST/ High Performance Analog Switches

Alternative Part Number

  • DG419DY --: Single SPDT analog switch with similar low on-resistance and pin-compatible SOIC package, widely available and a common drop-in replacement.
  • ADG419BRZ --: Precision SPDT analog switch offering comparable on-resistance and low leakage, suitable for signal routing in the same applications.
  • MAX4544ESA --: Low-voltage SPDT analog switch with similar electrical characteristics and small package, usable as a functional substitute.
