Description and Introduction

QUAD BUS BUFFERS (3-STATE) The M74HC125M1R is a quad buffer/line driver with 3-state outputs, manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Logic Family:** HC  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage Range:** 2V to 6V  
- **High-Level Output Current:** -5.2 mA  
- **Low-Level Output Current:** 5.2 mA  
- **Propagation Delay Time:** 13 ns at 5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** SO-14  

### **Descriptions:**  
The M74HC125M1R is a high-speed CMOS logic device that provides four independent buffer gates with 3-state outputs. It is designed for bus-oriented applications where multiple outputs may be connected to a common bus.  

### **Features:**  
- **High Noise Immunity**  
- **Low Power Consumption**  
- **Balanced Propagation Delays**  
- **Wide Operating Voltage Range (2V to 6V)**  
- **3-State Outputs for Bus Interface**  
- **Compatible with TTL Inputs**  
- **ESD Protection (HBM: 2 kV, MM: 200 V)**  

This device is commonly used in digital systems requiring buffering and signal isolation.

Application Scenarios & Design Considerations

QUAD BUS BUFFERS (3-STATE)

Alternative Part Number

  • SN74HC125DR --: Pin-compatible quad bus buffer with 3-state outputs in the same HC logic family, widely available and directly interchangeable in most designs.
  • MC74HC125ADG --: Equivalent quad 3-state buffer in HC family with matching function and pinout, suitable drop-in replacement with good availability.
  • CD74HC125E --: Same quad 3-state buffer function in HC logic, electrically compatible alternative from a different series naming for easy distinction.
  • MC74HC125ADR2G --: Equivalent quad 3-state buffer from the 74HC series, direct functional replacement with matching pinout and logic levels.
