Description and Introduction

Low-Voltage 4-Bit 1-Of-2 FET Multiplexer/Demultiplexer The SN74CBTLV3257D is a 4-bit 1-of-2 high-speed FET multiplexer/demultiplexer manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 2.3 V to 3.6 V  
- **Low On-State Resistance (Ron):** 5 Ω (typical)  
- **Bandwidth:** 200 MHz  
- **Low Power Consumption:** < 0.2 µA (max)  
- **Fast Switching:** tPD ≈ 0.25 ns (max)  
- **Input/Output Capacitance:** 10 pF (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16  

### **Descriptions:**  
- The SN74CBTLV3257D is designed for high-speed digital switching applications.  
- It provides bidirectional switching with minimal propagation delay and low power consumption.  
- Suitable for bus isolation, signal gating, and multiplexing/demultiplexing in low-voltage systems.  

### **Features:**  
- **Bidirectional Data Flow:** Allows multiplexing/demultiplexing in both directions.  
- **Low On-State Resistance:** Ensures minimal signal distortion.  
- **Wide Voltage Range:** Compatible with 2.5 V and 3.3 V systems.  
- **High Bandwidth:** Supports fast data transmission up to 200 MHz.  
- **Low Power Consumption:** Ideal for battery-powered applications.  
- **ESD Protection:** Exceeds 2000 V (HBM) for improved reliability.  

This device is commonly used in communication systems, data routers, and portable electronics.
