Description and Introduction

Low-Voltage 4-Bit 1-Of-2 FET Multiplexer/Demultiplexer The SN74CBTLV3257DR is a high-bandwidth FET bus switch manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Type:** 4-bit 1-of-2 FET multiplexer/demultiplexer  
- **Voltage Supply Range:** 2.3V to 3.6V  
- **On-State Resistance (Ron):** 5Ω (typical)  
- **Bandwidth:** 200 MHz  
- **Low Power Consumption:** 0.2µA (max) ICC  
- **Fast Switching:** tPD < 0.25ns  
- **Package:** SOIC-16  

### **Description:**  
The SN74CBTLV3257DR is designed for high-speed digital switching applications. It provides low on-state resistance and minimal propagation delay, making it suitable for multiplexing/demultiplexing signals in communication and computing systems.  

### **Features:**  
- **Low ON-State Resistance** (5Ω typical)  
- **Wide Voltage Range** (2.3V to 3.6V)  
- **High Bandwidth** (200 MHz)  
- **Bi-Directional Data Flow**  
- **Low Power Consumption**  
- **Supports Hot Insertion**  
- **ESD Protection** (≥2000V HBM)  

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

Application Scenarios & Design Considerations

Low-Voltage 4-Bit 1-Of-2 FET Multiplexer/Demultiplexer

Alternative Part Number

  • PI3B3257QEX --: Pin-compatible 4-bit 2:1 multiplexer/demultiplexer bus switch in SOIC-16, functionally equivalent to the SN74CBTLV3257 with similar low on-resistance and 3.3V operation.
  • CBT3257APW --: Quad 2:1 FET bus switch with the same 3257 function and pinout, widely used as a drop-in replacement for TI CBTLV3257 devices in TSSOP packages.
  • QS3257S1G --: Quad 2:1 high-speed CMOS bus switch offering equivalent switching behavior and pinout compatibility, suitable as an alternative when TI parts are unavailable.
