Description and Introduction

Single FET Bus Switch The SN74CBT1G125DBVT is a single bus switch gate manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Type:** Single FET Bus Switch  
- **Number of Channels:** 1  
- **Voltage Supply Range:** 1.65V to 5.5V  
- **On-State Resistance (Ron):** 5Ω (typical at 4.3V)  
- **Bandwidth:** 200MHz  
- **Input/Output Capacitance:** 5pF (typical)  
- **Propagation Delay:** 0.25ns (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The SN74CBT1G125DBVT is a high-bandwidth, low-power, single bus switch with an output enable (OE) control. It allows bidirectional switching between two ports when enabled and provides high isolation when disabled.  

### **Features:**  
- **Low On-State Resistance (Ron)**  
- **Wide Voltage Range (1.65V to 5.5V)**  
- **Fast Switching Speed**  
- **Low Power Consumption**  
- **Bidirectional Data Flow**  
- **5V Tolerant I/O with 3.3V Supply**  
- **ESD Protection Exceeds 2000V (HBM)**  
- **Small SOT-23-5 Package**  

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

Application Scenarios & Design Considerations

Single FET Bus Switch

Alternative Part Number

  • NC7SZ125P5X --: Single-gate bus switch with active-low output enable in a similar 5-pin package; widely available and functionally equivalent to the SN74CBT1G125.
  • 74LVC1G125GW,125 --: Single bus buffer/switch with 3-state output in a small SOT package; comparable logic function and voltage range, good second source.
  • SN74LVC1G125DBVR --: Same manufacturer single-gate 3-state buffer in the same SOT-23-5 footprint; different series prefix and pin-compatible logic alternative.
