Description and Introduction

Quadruple Bus Buffer Gates With 3-State Outputs The SN74ABT125DR is a quad bus buffer gate manufactured by Texas Instruments. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Technology Family:** ABT  
- **Supply Voltage Range:** 4.5V to 5.5V  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC (DR)  
- **Package Size:** 14-pin  
- **Propagation Delay (Max):** 4.5ns at 5V  
- **Input Logic Level - Low (Max):** 0.8V  
- **Input Logic Level - High (Min):** 2V  
- **Output Current (High/Low):** ±32mA  

### **Description:**
The SN74ABT125DR is a high-speed, low-power quad bus buffer gate with 3-state outputs. It is designed for driving heavily loaded bus lines or memory address registers while maintaining high-speed operation. The device features independent output-enable (OE) inputs for each buffer, allowing for flexible control.

### **Features:**
- **4-bit bus buffer with 3-state outputs**  
- **High-drive outputs (-32mA IOH, 64mA IOL)**  
- **BiCMOS technology for low power consumption**  
- **Latch-up performance exceeds 500mA per JESD 17**  
- **ESD protection exceeds 2000V per MIL-STD-883, Method 3015**  
- **Flow-through pinout for optimized PCB layout**  
- **Compatible with TTL input and output levels**  

This device is commonly used in applications such as bus interfacing, memory address buffering, and general-purpose logic buffering.
