Description and Introduction

Quadruple Bus Buffer Gates With 3-State Outputs The SN74HC125DBR is a quad bus buffer gate manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Buffer/Driver  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -7.8mA  
- **Low-Level Output Current:** 7.8mA  
- **Propagation Delay Time:** 11ns at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SSOP-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74HC125DBR is a high-speed CMOS logic device with four independent buffers.  
- It features 3-state outputs, allowing multiple outputs to be connected to a common bus.  
- Designed for bus-oriented applications where outputs can be disabled when not in use.  

### **Features:**  
- **3-State Outputs:** Enable/disable control for bus applications.  
- **Wide Operating Voltage:** 2V to 6V.  
- **Balanced Propagation Delays:** Ensures signal integrity.  
- **Low Power Consumption:** CMOS technology minimizes power usage.  
- **High Noise Immunity:** Ensures reliable operation in noisy environments.  
- **ESD Protection:** Exceeds JESD 22 standards (2000V HBM, 1000V CDM).

Application Scenarios & Design Considerations

Quadruple Bus Buffer Gates With 3-State Outputs

Alternative Part Number

  • MC74HC125ADTR2G --: Quad buffer with 3-state outputs in the same HC logic family, TSSOP-14 package, direct functional and pin-compatible replacement.
  • 74HC125PW,118 --: Equivalent quad 3-state buffer in HC family, TSSOP-14 package, widely available and pin-compatible with the original.
  • CD74HC125M96 --: Same manufacturer HC-family quad 3-state buffer, SOIC-14 package, electrically equivalent though package differs from the original TSSOP.
