Description and Introduction

OCTAL BUS BUFFER INVERTING/NON-INVERTING, 3-STATE OUTPUTS The **TC74HC541AFW** is a high-speed CMOS octal buffer and line driver manufactured by **TOSHIBA**. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Logic Type:** Octal Buffer/Line Driver  
- **Technology:** High-Speed CMOS (HC)  
- **Supply Voltage Range (VCC):** 2V to 6V  
- **Input Voltage Range (VI):** 0V to VCC  
- **Operating Temperature Range:** -40°C to +85°C  
- **Output Current (IO):** ±7mA (at VCC = 4.5V)  
- **Propagation Delay (tpd):** 13ns (max) at VCC = 4.5V  
- **Input Capacitance (CI):** 3.5pF (typ)  
- **Package Type:** TSSOP-20  

### **Descriptions:**  
- The **TC74HC541AFW** is an **8-bit non-inverting buffer/line driver** with **3-state outputs**.  
- Designed for **bus-oriented applications**, it provides **high-speed operation** while maintaining low power consumption.  
- Features **output enable (OE) inputs** for bus isolation.  

### **Features:**  
- **Non-inverting outputs** for signal buffering.  
- **3-state outputs** allow connection to a bus system.  
- **Wide operating voltage range (2V to 6V)** for compatibility with TTL and CMOS logic levels.  
- **Balanced propagation delays** for reliable timing.  
- **Low power consumption** (ICC = 4µA max at 25°C).  
- **High noise immunity** due to CMOS technology.  

This device is commonly used in **data communication, memory interfacing, and bus driving applications**.
