Description and Introduction

10-Bit FET Bus-Exchange Switches with -2 V Undershoot Protection The SN74CBT3383CDBQR is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 10-Bit FET Bus Switch  
- **Voltage Supply Range:** 4V to 5.5V  
- **On-State Resistance (Ron):** 5Ω (typical)  
- **Bandwidth:** 200MHz  
- **Propagation Delay:** 0.25ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP (DBQ) – 20-pin  

### **Descriptions:**  
The SN74CBT3383CDBQR is designed for high-speed digital switching applications. It provides low on-state resistance and minimal propagation delay, making it suitable for bus isolation and signal routing in mixed-voltage systems.  

### **Features:**  
- **Low On-State Resistance (5Ω typical)**  
- **TTL-Compatible Input Levels**  
- **Supports 5V and 3.3V Mixed-Voltage Operation**  
- **Fast Switching (0.25ns propagation delay)**  
- **High Bandwidth (200MHz)**  
- **Bi-Directional Data Flow**  
- **ESD Protection (2000V HBM, 1000V CDM)**  

This device is commonly used in digital systems for signal routing, bus isolation, and hot-swapping applications.

Application Scenarios & Design Considerations
