Description and Introduction

OCTAL BUS BUFFER WITH TTL INPUT LEVEL. INVERTING/NON-INVERTING, 3-STATE OUTPUTS The TC74HCT540AP is a high-speed CMOS logic octal bus buffer manufactured by Toshiba. Below are its specifications, descriptions, and features based on factual data:

### **Manufacturer:**  
Toshiba  

### **Specifications:**  
- **Logic Family:** HCT (High-Speed CMOS, TTL-Compatible)  
- **Number of Channels:** 8 (Octal)  
- **Input Type:** TTL-Compatible  
- **Output Type:** 3-State  
- **Supply Voltage Range (VCC):** 4.5V to 5.5V  
- **High-Level Input Voltage (VIH):** 2V (min)  
- **Low-Level Input Voltage (VIL):** 0.8V (max)  
- **High-Level Output Voltage (VOH):** 4.4V (min) @ IOH = -6mA  
- **Low-Level Output Voltage (VOL):** 0.1V (max) @ IOL = 6mA  
- **Propagation Delay Time (tpd):** 15ns (max) @ VCC = 4.5V, CL = 50pF  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** DIP-20 (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The TC74HCT540AP is an octal inverting buffer/line driver with 3-state outputs.  
- It is designed for bus-oriented applications where multiple devices share a common bus.  
- The 3-state outputs allow the device to be disconnected from the bus when not in use.  
- It is compatible with TTL levels, making it suitable for interfacing between TTL and CMOS systems.  

### **Features:**  
- **Octal Inverting Buffer:** 8 channels with inverted outputs.  
- **3-State Outputs:** Allows high-impedance state for bus sharing.  
- **TTL-Compatible Inputs:** Works with TTL logic levels.  
- **Wide Operating Voltage:** 4.5V to 5.5V supply range.  
- **High-Speed Operation:** Low propagation delay for fast signal transmission.  
- **Low Power Consumption:** CMOS technology ensures low power dissipation.  
- **ESD Protection:** Provides protection against electrostatic discharge.  

This information is based on Toshiba's datasheet for the TC74HCT540AP.
