- **Package:** SSOP-16 (DBQ)  

### **Descriptions:**  
The SN74CB3Q3257DBQR is a high-speed, low-power bus switch designed for multiplexing/demultiplexing signals in digital systems. It provides bidirectional switching with minimal propagation delay and supports hot insertion.  

### **Features:**  
- **Bidirectional Data Flow**  
- **Low On-State Resistance (5Ω typical)**  
- **Fast Switching (tPD ~0.25ns)**  
- **Supports Mixed-Mode Signal Operation**  
- **5V Tolerant I/Os with 3.3V Supply**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds 2000V per JESD 22**  

This device is commonly used in signal routing, bus isolation, and level translation applications.
