Description and Introduction

Low-Voltage 20-Bit FET Bus Switch With Precharged Outputs The SN74CBTLV16800VR is a high-bandwidth FET bus switch manufactured by Texas Instruments (TI). Below are the factual details from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments (TI)  

### **Pb-Free Specifications:**  
- The device is **Pb-free (RoHS compliant)**.
- It is **Green (halogen-free and environmentally friendly)**.  

### **Descriptions:**  
- The SN74CBTLV16800VR is a **20-bit FET bus switch** with low ON-state resistance (ron), enabling minimal propagation delay.
- It supports **bidirectional data flow** with near-zero propagation delay.
- The device operates with **3.3V VCC** and is compatible with 5V input signals.
- It features **high-bandwidth switching** for high-speed data transfer applications.

### **Features:**  
- **20-bit bus switch** with independent control inputs.
- **Low ON-state resistance (ron):** 5Ω (typical).
- **Bandwidth:** 200 MHz (typical).
- **5V tolerant I/Os** (with 3.3V VCC).
- **Supports hot insertion** (Ioff protection).
- **Minimal propagation delay:** < 0.25 ns.
- **Latch-up performance exceeds 250 mA per JESD 17.**
- **ESD protection:**  
  - 2000V Human-Body Model (HBM)  
  - 1000V Charged-Device Model (CDM)  

### **Package:**  
- **TSSOP (VR) – 56-pin**  

This information is strictly based on the available specifications and features of the SN74CBTLV16800VR.

Application Scenarios & Design Considerations

Low-Voltage 20-Bit FET Bus Switch With Precharged Outputs

Alternative Part Number

  • PI3B16800A --: Pin-compatible 16-bit bus switch with similar low-voltage operation and low on-resistance, suitable as a functional replacement.
  • CBT16800DGG --: 16-bit CBT-series bus switch offering comparable switching characteristics and TSSOP packaging for direct board-level substitution.
  • QS3VH16800PA --: 3.3V 16-bit bus switch with similar bandwidth and low propagation delay, usable as an alternative in bus isolation applications.
  • PI3C16800V --: Low-voltage 16-bit bus switch with similar 24-bit/16-bit bus exchange function and 3.3V operation, drop-in functional alternative in a different series.
  • CBT16211DGG --: 16-bit bus switch with similar low-voltage switching characteristics; check pinout and exchange function before substitution.
