Description and Introduction

1-of-8 FET Multiplexer/Demultiplexer The TC7MB3251FK is a digital switch IC manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Toshiba  
- **Type:** Single-Pole Double-Throw (SPDT) Analog Switch  
- **Configuration:** 2-channel  
- **Supply Voltage Range (VDD):** 1.65V to 5.5V  
- **On-Resistance (RON):** 5Ω (typical at VDD = 4.5V)  
- **Low Power Consumption:** 0.1μA (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** VSSOP (Very Small Outline Package)  
- **Pin Count:** 8  

### **Descriptions:**  
The TC7MB3251FK is a CMOS-based analog switch IC designed for low-voltage, high-speed signal switching applications. It features low on-resistance and minimal power consumption, making it suitable for portable and battery-operated devices.  

### **Features:**  
- **Wide Operating Voltage:** Supports 1.65V to 5.5V, compatible with various logic levels.  
- **Low On-Resistance:** Ensures minimal signal distortion.  
- **Bidirectional Switching:** Allows signals to pass in both directions.  
- **Fast Switching Speed:** Suitable for high-frequency applications.  
- **Low Power Consumption:** Ideal for power-sensitive designs.  
- **Break-Before-Make Function:** Prevents signal overlap during switching.
