Description and Introduction

Octal Buffers and Line Drivers with 3-State Outputs The SN74LS540DBR is a part manufactured by Texas Instruments. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Texas Instruments  
- **Category:** Integrated Circuits (ICs)  
- **Series:** 74LS  
- **Logic Type:** Buffer/Line Driver  
- **Number of Bits:** 8  
- **Output Type:** 3-State  
- **Voltage Supply:** 4.75V to 5.25V  
- **Operating Temperature:** 0°C to 70°C  
- **Package / Case:** SSOP-20  
- **Mounting Type:** Surface Mount  
- **Propagation Delay Time:** 15 ns (max)  
- **Current - Output High, Low:** 15mA, 24mA  

### **Descriptions:**  
The SN74LS540DBR is an octal buffer and line driver with 3-state outputs. It is designed to provide high-speed, low-power operation and is compatible with TTL (Transistor-Transistor Logic) inputs. The device is commonly used in bus-oriented systems where multiple outputs must be isolated from a shared bus.  

### **Features:**  
- **Octal Buffer/Line Driver** with 3-state outputs  
- **Inverting Logic** (outputs are inverted from inputs)  
- **High-Current Outputs** for driving bus lines  
- **TTL-Compatible** inputs and outputs  
- **Wide Operating Voltage Range** (4.75V to 5.25V)  
- **Low Power Consumption** (typical 32mW)  
- **ESD Protection** on all inputs and outputs
