Description and Introduction

4-Bit 1-Of-2 FET Multiplexer/Demultiplexer The SN74CBT3257PW is a high-speed TTL-compatible FET bus switch manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TEXAS)  
- **Type:** 4-bit 1-of-2 FET multiplexer/demultiplexer  
- **Technology:** CMOS  
- **Supply Voltage Range (VCC):** 4V to 5.5V  
- **On-State Resistance (RON):** 5Ω (typical)  
- **Bandwidth:** 200 MHz  
- **Propagation Delay:** 0.25 ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16 (PW)  

### **Descriptions:**  
The SN74CBT3257PW is a high-bandwidth, low-impedance bus switch designed for digital and analog signal switching. It supports bidirectional data flow and is compatible with TTL-level signals. The device features four independently controlled 1-of-2 multiplexers/demultiplexers, making it suitable for signal routing in communication systems, data acquisition, and bus isolation applications.

### **Features:**  
- **Low On-State Resistance (5Ω typical)**  
- **Fast Switching (0.25 ns propagation delay)**  
- **TTL-Compatible Input Levels**  
- **4.5V to 5.5V Supply Voltage Operation**  
- **Supports Both Analog and Digital Signals**  
- **Bidirectional Data Flow**  
- **Low Power Consumption**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Packaged in 16-Pin TSSOP (PW)**  

This device is commonly used in signal routing, bus isolation, and multiplexing applications in various electronic systems.
