Description and Introduction

Quadruple FET Bus Switch The SN74CBT3125DGVR is a quad 1-bit bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Configuration:** Quad 1-bit bus switch  
- **Number of Channels:** 4  
- **Voltage Supply Range (VCC):** 4V to 5.5V  
- **On-State Resistance (RON):** 5Ω (typical)  
- **Bandwidth:** 200MHz  
- **Propagation Delay:** 0.25ns (typical)  
- **Input/Output Capacitance:** 10pF (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TVSOP (8-pin)  

### **Descriptions:**  
The SN74CBT3125DGVR is a high-speed, low-power bus switch designed for digital signal switching applications. It features low on-state resistance and minimal propagation delay, making it suitable for high-speed data routing.  

### **Features:**  
- Low on-state resistance (5Ω typical)  
- Fast switching (200MHz bandwidth)  
- Minimal propagation delay (0.25ns typical)  
- 5V TTL-compatible inputs  
- Supports mixed-mode signal operation  
- Bidirectional data flow  
- ESD protection exceeds 2000V (HBM)  

This device is commonly used in signal multiplexing, bus isolation, and level shifting applications.

Application Scenarios & Design Considerations

Quadruple FET Bus Switch

Alternative Part Number

  • PI3B3125LE --: Quad bus switch with similar 4-bit 2:1 mux/demux function and low on-resistance, pin-compatible in many designs and widely available as a TI CBT3125 replacement.
  • QS3VH125QG8 --: Quad 2:1 bus switch with low propagation delay and 3.3V operation, functionally equivalent to the SN74CBT3125 and suitable for signal switching applications.
  • 74CBTLV3125PGG8 --: Low-voltage quad bus switch in the CBTLV family offering similar 4-bit switching behavior and 3.3V compatibility, a common cross-reference for CBT3125 devices.
