Description and Introduction

Quadruple FET Bus Switch 14-TSSOP -40 to 85 The SN74CBT3126PWRG4 is a quad 1-bit bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Supply Voltage Range:** 4 V to 5.5 V  
- **On-State Resistance (RON):** 5 Ω (typical)  
- **Bandwidth:** 200 MHz  
- **Low Power Consumption:** 0.25 µA (max) ICC  
- **Fast Switching:** tPD < 0.25 ns  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-14  

### **Descriptions:**  
The SN74CBT3126PWRG4 is a high-speed, low-power bus switch designed for digital signal switching. It features four independently controlled 1-bit switches with low on-state resistance, ensuring minimal signal distortion.  

### **Features:**  
- Low on-state resistance for minimal signal attenuation  
- Supports bidirectional voltage translation  
- 5 V tolerant inputs with 3.3 V supply  
- Fast switching for high-speed applications  
- Break-before-make switching to prevent signal contention  
- ESD protection exceeds 2000 V (HBM)  

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

Application Scenarios & Design Considerations

Quadruple FET Bus Switch 14-TSSOP -40 to 85

Alternative Part Number

  • PI5C3126Q --: Quad bus switch with similar 4-bit 2:1 mux/demux function and low on-resistance, direct functional equivalent to the CBT3126 family.
  • QS3VH126Q --: Quad 2:1 bus switch with comparable low propagation delay and 5V tolerant I/O, suitable drop-in replacement for CBT3126 applications.
  • 74CBTLV3126PW --: Low-voltage quad bus switch in TSSOP package with similar switching characteristics and pinout, widely used as CBT3126 alternative.
