Description and Introduction

Octal Buffers/Drivers With 3-State Outputs The SN74AHCT540N is a part manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Logic Type:** Inverting Buffer/Driver  
- **Technology Family:** AHCT  
- **Supply Voltage (VCC):** 4.5V to 5.5V  
- **Number of Channels:** 8  
- **Input Type:** Schmitt Trigger  
- **Output Type:** 3-State  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package/Case:** PDIP-20 (Plastic Dual In-Line Package)  
- **Propagation Delay Time:** 9.5 ns (typical at 5V)  
- **High-Level Output Current:** -8 mA  
- **Low-Level Output Current:** 8 mA  

### **Descriptions:**  
The SN74AHCT540N is an octal buffer and line driver with 3-state outputs. It is designed for 5V VCC operation and features inverting outputs. The device is ideal for driving high-capacitance loads and low-impedance loads due to its high-drive capability. The 3-state outputs allow multiple devices to be connected to a common bus without interference.  

### **Features:**  
- **Inverting Logic:** Provides inverted outputs relative to inputs.  
- **3-State Outputs:** Allows bus-oriented applications.  
- **Schmitt-Trigger Inputs:** Improves noise immunity.  
- **Wide Operating Voltage:** 4.5V to 5.5V.  
- **Balanced Propagation Delays:** Ensures consistent performance.  
- **High Drive Capability:** Supports up to ±8 mA output current.  
- **ESD Protection:** Exceeds 2000V per JESD 22.  

This information is strictly based on the manufacturer's datasheet and specifications.
