Description and Introduction

Octal FET Bus Switch The SN74CBT3244DWR is a 10-bit bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 10-bit FET bus switch  
- **Voltage Supply Range:** 4V to 5.5V  
- **On-State Resistance (Max):** 5Ω  
- **Bandwidth:** 200MHz  
- **Propagation Delay:** 0.25ns (Max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC (DW)  

### **Descriptions and Features:**  
- **High-Speed Switching:** Supports fast data transmission with minimal propagation delay.  
- **Low On-State Resistance:** Ensures minimal signal distortion.  
- **5V Tolerant I/Os:** Compatible with mixed-voltage systems.  
- **Bi-Directional Operation:** Allows data flow in both directions.  
- **Low Power Consumption:** Reduces overall system power usage.  
- **ESD Protection:** Provides robustness against electrostatic discharge.  

This device is commonly used in signal routing, hot-swapping, and level-shifting applications.

Application Scenarios & Design Considerations

Octal FET Bus Switch

Alternative Part Number

  • PI3B3244QE --: Pin-compatible 8-bit bus switch with similar 4.5 ohm on-resistance and 5V operation, direct functional replacement in SOIC-20 style packages.
  • QS3244SO --: Quad 2:1 bus switch/multiplexer with comparable low on-resistance and 5V TTL-compatible control inputs, widely used as a CBT3244 substitute.
  • 74CBTLV3244QG --: Low-voltage 8-bit bus switch with similar bus-exchange function and pinout, suitable when 3.3V operation is acceptable.
