Description and Introduction

Quad 3-state buffer The SN74LS125AN is a quad bus buffer gate with 3-state outputs manufactured by Texas Instruments (TI) and Motorola (MOT).  

### **Specifications:**  
- **Logic Family:** LS (Low-Power Schottky)  
- **Number of Channels:** 4 (Quad)  
- **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 (tpd):** 15 ns (typical)  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package Type:** PDIP-14 (Plastic Dual In-Line Package)  

### **Descriptions:**  
The SN74LS125AN is a quad bus buffer designed to provide high-speed, low-power operation with 3-state outputs. It is commonly used in bus-oriented applications where multiple devices share a common bus. Each of the four buffers has an independent output enable (OE) input, allowing individual control of the output state.  

### **Features:**  
- **3-State Outputs:** Allows connection to a bus system without loading.  
- **Independent Output Enable Controls:** Each buffer can be enabled/disabled separately.  
- **High-Speed Operation:** Typical propagation delay of 15 ns.  
- **Low Power Consumption:** LS technology ensures efficient power usage.  
- **Wide Operating Voltage Range:** Supports standard TTL levels.  
- **Standard Pinout:** Compatible with industry-standard 14-pin DIP packages.  

This device is widely used in digital systems for signal buffering, bus driving, and interfacing applications.
