Description and Introduction

4-Bit 1-Of-2 FET Multiplexer/Demultiplexer with -2 V Undershoot Protection The SN74CBT3257CDBR is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 4-bit 1-of-2 FET multiplexer/demultiplexer  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **On-State Resistance (Ron):** 5Ω (typical)  
- **Bandwidth:** 200MHz (typical)  
- **Low Power Consumption:** 0.25µA (max) ICC  
- **Fast Switching:** tPD = 0.25ns (max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SSOP-16  

### **Descriptions:**  
The SN74CBT3257CDBR is designed for high-speed bus switching applications. It allows bidirectional signal flow with minimal propagation delay and low on-state resistance. It is compatible with TTL-level inputs and can be used in multiplexing/demultiplexing configurations.  

### **Features:**  
- **Low On-State Resistance (5Ω typical)**  
- **TTL-Compatible Control Inputs**  
- **Supports Mixed-Mode Signal Operation**  
- **Bidirectional Data Flow**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  
- **ESD Protection Exceeds 2000V per JESD 22**  

This device is commonly used in data routing, signal gating, and bus isolation in digital systems.
