Description and Introduction

QUAD BUS BUFFERS (3-STATE) The M74HCT125RM13TR is a quad buffer/line driver with 3-state outputs, manufactured by STMicroelectronics.  

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -6mA  
- **Low-Level Output Current (IOL):** 6mA  
- **Propagation Delay (tpd):** 13ns (typical) at 4.5V  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** SO-14  

### **Descriptions:**  
- The M74HCT125RM13TR is a high-speed CMOS logic device that provides four independent buffer gates with 3-state outputs.  
- It is designed for interfacing with TTL levels while operating from a 5V supply.  
- The 3-state outputs allow multiple devices to share a common bus without interference.  

### **Features:**  
- **High Noise Immunity:** CMOS technology ensures low power consumption and high noise immunity.  
- **Wide Operating Voltage Range:** Compatible with TTL levels (4.5V to 5.5V).  
- **3-State Outputs:** Enables bus-oriented applications.  
- **High-Speed Operation:** Low propagation delay for efficient performance.  
- **Low Power Consumption:** Ideal for battery-operated devices.  
- **ESD Protection:** Improved reliability with built-in electrostatic discharge protection.  

This information is based solely on the manufacturer's datasheet.
