Description and Introduction

Low-Voltage Quadruple FET Bus Switch The SN74CBTLV3126D is a quad bus switch manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Quad FET Bus Switch  
- **Number of Channels:** 4  
- **Voltage Supply Range:** 2.3V to 3.6V  
- **On-State Resistance (Max):** 10Ω at 3.3V  
- **Bandwidth:** 200 MHz  
- **Propagation Delay:** 0.25 ns (Max)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-14  

### **Descriptions:**  
The SN74CBTLV3126D is a high-bandwidth, low-voltage quad bus switch designed for multiplexing and signal routing in digital systems. It provides minimal propagation delay and supports bidirectional data flow.  

### **Features:**  
- Low ON-state resistance (10Ω typical at 3.3V)  
- Supports mixed-mode signal operation  
- Bidirectional data flow with near-zero propagation delay  
- 5V-tolerant I/O ports (with 3.3V supply)  
- Latch-up performance exceeds 250 mA per JESD 17  
- ESD protection exceeds 2000V per JESD 22  

This device is commonly used in signal switching, bus isolation, and level translation applications.

Application Scenarios & Design Considerations

Low-Voltage Quadruple FET Bus Switch

Alternative Part Number

  • PI3B3126Q --: Quad bus switch with similar 4-bit 2:1 mux/demux function and low on-resistance, direct functional replacement for the SN74CBTLV3126D in bus-switching applications.
  • 74CBTLV3126QG --: Same CBTLV3126 function from a different vendor, quad FET bus switch with low propagation delay, pin-compatible alternative when TI part is unavailable.
  • NC7SZ126P5X --: Single bus switch buffer with similar low-voltage CBTLV logic family characteristics; usable as a substitute in designs where only one channel is needed or where a smaller package is acceptable.
