Description and Introduction

20-Bit FET Bus Switch The SN74CBT16861DLR is a 24-bit bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** 24-bit FET bus switch  
- **Voltage Supply Range:** 4V to 5.5V  
- **On-State Resistance (Ron):** 5Ω (typical)  
- **Bandwidth:** 200MHz  
- **Number of Channels:** 24  
- **Package:** SSOP (DLR)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Switching Time:** 5ns (max)  

### **Descriptions:**  
The SN74CBT16861DLR is a high-bandwidth FET bus switch designed for digital and analog signal switching. It provides low on-state resistance and minimal propagation delay, making it suitable for high-speed data routing.  

### **Features:**  
- Low on-state resistance (5Ω typical)  
- Supports both digital and analog signals  
- 5V tolerant inputs  
- Bidirectional switching capability  
- Minimal propagation delay  
- High bandwidth (200MHz)  
- ESD protection (2000V HBM)  

This device is commonly used in communication systems, data routing, and signal multiplexing applications.

Application Scenarios & Design Considerations

20-Bit FET Bus Switch

Alternative Part Number

  • PI3C16861A --: Pericom 24-bit bus switch with similar 20-bit/24-bit CBT function and low propagation delay, direct functional replacement in the same package family.
  • QS3C16861 --: IDT QuickSwitch bus switch offering comparable 24-bit CBT switching characteristics and 5V tolerant I/O, suitable drop-in alternative.
  • CBT16861DGG --: NXP CBT-series 24-bit bus switch with equivalent low ON-resistance and near-zero propagation delay, widely available alternative.
  • PI3B16861A --: Pin-compatible 20-bit bus switch with similar 5V bus-switch function and low on-resistance, direct functional replacement in most designs.
  • QS3VH16861 --: 20-bit QuickSwitch bus switch with comparable bandwidth and low propagation delay, suitable as a functional alternative.
