Description and Introduction

4-Bit 1-Of-2 FET Multiplexer/Demultiplexer with -2 V Undershoot Protection 16-SOIC -40 to 85 The SN74CBT3257CDG4 is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments  
- **Category:** Switches - Analog Switches, Multiplexers, Demultiplexers  
- **Series:** 74CBT  
- **Package:** SOIC-16  
- **Switch Type:** SPDT (Single Pole Double Throw)  
- **Number of Channels:** 4  
- **On-State Resistance (Max):** 5Ω  
- **Voltage Supply (Single):** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Bandwidth:** 200MHz  
- **Propagation Delay Time:** 0.25ns  
- **Crosstalk:** -50dB @ 10MHz  

### **Description:**
The SN74CBT3257CDG4 is a 4-bit 1-of-2 high-speed FET multiplexer/demultiplexer. It provides low on-state resistance and minimal propagation delay, making it suitable for high-speed switching applications. It is compatible with TTL-level inputs and operates within a 5V supply range.

### **Features:**
- **Low On-State Resistance (5Ω typical)**  
- **TTL-Compatible Input Levels**  
- **Fast Switching (0.25ns typical propagation delay)**  
- **High Bandwidth (200MHz)**  
- **Bi-Directional Data Flow**  
- **Supports Mixed-Mode Signal Operation**  
- **ESD Protection (HBM > 2000V)**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  

This device is commonly used in signal routing, data switching, and bus isolation applications.  

(Note: All information is based on the manufacturer's datasheet.)
