Description and Introduction

Quadruple Bus Buffer Gates With 3-State Outputs The SN74AHCT125PWR is a quad bus buffer gate manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Buffer/Line Driver, Non-Inverting  
- **Number of Channels:** 4  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **High-Level Input Voltage (Min):** 2V  
- **Low-Level Input Voltage (Max):** 0.8V  
- **Output Current (High/Low):** ±8mA  
- **Propagation Delay Time:** 8.5ns (Max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** TSSOP-14  
- **Mounting Type:** Surface Mount  

### **Descriptions:**  
- The SN74AHCT125PWR is a high-speed CMOS logic device with 3-state outputs.  
- It is designed for bus-oriented applications where multiple devices share a common bus.  
- The outputs can be disabled using the output-enable (OE) input, placing them in a high-impedance state.  

### **Features:**  
- **4-Channel Buffer with 3-State Outputs**  
- **Compatible with TTL Input Levels**  
- **Balanced Propagation Delays**  
- **Low Power Consumption**  
- **ESD Protection Exceeds 2000V per JESD 22**  
- **Wide Operating Voltage Range (4.5V to 5.5V)**  
- **Latch-Up Performance Exceeds 250mA per JESD 17**  

This device is commonly used in digital systems for signal buffering and bus driving applications.
