Description and Introduction

Low-Voltage/ Single Supply/ Dual SPST/ SPDT Analog Switches The ISL5121IB is a high-speed, low-power dual SPST (Single Pole Single Throw) 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 +4.5V to +40V (Single Supply)  
- **On-Resistance (RON):** 45Ω (Typical)  
- **On-Resistance Flatness (RFLAT):** 5Ω (Typical)  
- **Charge Injection:** 10pC (Typical)  
- **Bandwidth (-3dB):** 100MHz (Typical)  
- **Switching Time (tON/tOFF):** 150ns / 100ns (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Lead SOIC  

### **Description:**
The ISL5121IB is a precision, dual-channel analog switch designed for high-performance signal switching applications. It offers low on-resistance, fast switching speeds, and excellent signal integrity, making it suitable for audio, video, and data acquisition systems.

### **Features:**
- **Low On-Resistance (45Ω)** for minimal signal distortion  
- **Wide Supply Voltage Range** (±4.5V to ±20V or +4.5V to +40V)  
- **Fast Switching Speeds** (150ns turn-on, 100ns turn-off)  
- **High Bandwidth (100MHz)** for signal fidelity  
- **Low Charge Injection (10pC)** for reduced glitches  
- **Break-Before-Make Switching** to prevent signal overlap  
- **TTL/CMOS Compatible Logic Inputs**  
- **ESD Protection:** 2kV (HBM)  

This switch is ideal for applications requiring high-speed signal routing with minimal distortion.
