Description and Introduction

8-Bit 2.5-V/3.3-V Low-Voltage FET Bus Switch The SN74CB3Q3245 is a high-bandwidth FET bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Technology:** CMOS  
- **Supply Voltage Range (VCC):** 2.3V to 3.6V  
- **Number of Channels:** 8  
- **On-State Resistance (RON):** 5Ω (typical)  
- **Bandwidth:** 500 MHz (typical)  
- **Propagation Delay:** 0.25 ns (typical)  
- **Input/Output Capacitance (CI/O):** 7 pF (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Options:** TSSOP, TVSOP, BGA  

### **Descriptions:**  
The SN74CB3Q3245 is an 8-bit bus switch with low on-state resistance, enabling high-speed signal switching with minimal propagation delay. It supports bidirectional data flow and is designed for high-performance digital systems.  

### **Features:**  
- **Low On-State Resistance (RON)** for minimal signal distortion  
- **Bi-Directional Data Flow** with no direction control required  
- **Supports Mixed-Mode Signal Operation** (5V inputs with 3.3V VCC)  
- **Near-Zero Propagation Delay** for high-speed switching  
- **Low Power Consumption** (ICC ≈ 0 when disabled)  
- **5V Tolerant I/Os** for compatibility with higher voltage systems  
- **ESD Protection** exceeds 2000V (HBM)  

This device is commonly used in digital systems requiring fast signal switching, such as data buses, memory interfaces, and communication ports.
