Description and Introduction

Octal Buffers And Line Drivers With 3-State Outputs The SN74HCT240N is a high-speed CMOS logic octal buffer and line driver with 3-state outputs, manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Logic Type:** Inverting Buffer/Line Driver  
- **Number of Channels:** 8  
- **Output Type:** 3-State  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Current (IOH):** -6mA  
- **Low-Level Output Current (IOL):** 6mA  
- **Propagation Delay (tpd):** 18ns (max) at 5V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
The SN74HCT240N is designed for bus-oriented applications where multiple devices share a common bus. It features inverting outputs and separate output-enable (OE) inputs for each 4-bit buffer, allowing flexible control.  

### **Features:**  
- **Wide Operating Voltage Range:** 4.5V to 5.5V  
- **Low Power Consumption:** CMOS technology  
- **High Noise Immunity:** HCT input levels  
- **3-State Outputs:** Allows connection to a bus system  
- **Balanced Propagation Delays**  
- **ESD Protection:** Exceeds 2000V per JESD 22  

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