Description and Introduction

Quad 3-state buffer The SN74LS126AD is a quad bus buffer gate manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Bus Buffer/Driver  
- **Number of Channels:** 4  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.75V to 5.25V  
- **High-Level Output Current (IOH):** -2.6 mA  
- **Low-Level Output Current (IOL):** 24 mA  
- **Propagation Delay Time (tpd):** 15 ns (max)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** SOIC-14  

### **Descriptions:**  
The SN74LS126AD is a quadruple bus buffer with 3-state outputs. Each buffer has an independent output-enable (OE) input that places the output in a high-impedance state when driven high.  

### **Features:**  
- **3-State Outputs:** Allow multiple devices to share a common bus.  
- **High-Current Outputs:** Drive up to 24 mA at low levels.  
- **TTL-Compatible Inputs:** Ensures compatibility with standard TTL logic levels.  
- **Wide Operating Voltage Range:** Supports standard 5V logic systems.  
- **Independent Enable Controls:** Each buffer has its own output-enable pin.  

This device is commonly used in bus-oriented systems where multiple drivers share a common data line.
